Energy Conversions

[kenhung123]

This is so confusing. In electrolysis batteries function to pull e's from the reductant and supply it to the oxidant. The conversion is electrical to chemical, now where is this electrical energy stored in chemical? If you say as the oxidant uses e's then how come the energy conversion in Galvanic, the conversion is chemical to electrical? As in both cases, e's are consumed (stored)

ok im a little confused on what your asking
but let me try to give you a overview of how i see it and hopefully you will get it.

in galvanic cells
we are putting in electrical energy ( from the power source) and getting out chemical energy and heat ( THE TEMP RISES)
in galvanic cells . the reactions are SPONTANEOUS , that is . they do not need extra "force" for the electrons to flow from annode to cathode.... therefore . the anode is negative and the cathode is positive .. ( anions( negetive ions) go to the annode , cations ( positive ions) to go the cathode).

keep inmind .. galvanic cells are exothermic ( mostly) .. and therefore ... just like all chemical reactions . the reactants want to get from high energy state .. to a low energy state . and so they react spontaneously..

however
in ELECTROLYTIC cells.
the power source FORCES the elctrons from the annode to the cathode.
it withdraws electrons .. and take them .. it is not spontaneous
therefore .... since the electrons are being FORCED out .. the annode becomes positive . .. and the cathode becomes negetive. . ( its the complete opposite to galvanic cells)
but
keep inmind
in electrolytic cells .. . we are putting in chemical energy ( chemical reactions)
and forcing the reaction to happen ... and getting electricitty out of it



some 1 plz correct me im wrong with anything
but thats the way i see it
i hope it helps
goodluck.

KEEP INMIND
IN ELECTROLYTIC AND IN GALVANIC CELLS
REDUCTION OCCURS AT CATHODE AND OXIDATION OCCURS AT ANNODE.

EDIT : also keep inmind .. electrolytic cells in most cases are like endothermic reactions ( there needs to be alot of energy supplied for it to work)  and so . when they get to the higher state .. they will want to react spontaneously to get lower .. but we prevent this using a seperator . such as porous barrier "
goodluck

[kenhung123]

Can you please tell me what is the chemical and what is the electrical in both galvanic and electrolytic cells

[matt123]

Can you please tell me what is the chemical and what is the electrical in both galvanic and electrolytic cells

umm im a little lost in what your asking

in galvanic cells .. you have chemicals in 2 beakers ( the chemicals are what ever you chose)
the electrical .. is the power source pumping electrons ( electricity)
the electrical energy ( power sources) provides enough electricity for the reaction ... ,.. which creates heat energy.
in other words
electrical energy becomes chemical energy

in ELECTROLYSIS however
you have 2 chemicals in 1 cell ( what everr 2 chemicals you chose ..) .... they react FORCEFULLY/NON SPONTANEOUSLY .. which releases electricity.

make sence?

You are confused between galvanic and electrolytic in some regards. Galvanic cells do not require a power source, as they are creating electricity themselves. The conversion of energy is from chemical to electrical, not electrical to chemical. In electrolytic cells, you require energy (in the form of electricity) to drive the reaction forward, and you are not converting chemical to electrical, but rather electrical to chemical.

You probably do know this (I am preety sure) but I'd add that the reason you're allowed to do this is due to the fact that the potential difference is greater. Which as you said "drive" or "forces" the reaction in that way.

oehh yeh ofcourse
thanks for the correction
yeh i shud edit that
i shoudlnt have said energy source for galvanic
thats just dumb rofl
i think i was just typing quick trying to respond . didnt realise what i wrote

thankx braa

OK so in electrolysis, the power source electrical is converted to chemical energy present where? From the absorption of electrons?

in electrolysis
the CHEMICAL REACTIONS "make" the elctrical energy.
the power source just FORCES the electrons away from the anode and to the cathode .. its non spontaneous.
i dont know what you mean "absorbtion of cathode"
what happens is ... at the cathode  .. reduction occurs ... AND the electrons arrive ... therefore the cathode becomes negative.

[kenhung123]

Im not asking about polarities or how electrolysis works. I am just having trouble identifying what the textbook means by "electrical energy" and "chemical energy" in galvanic and electrolysis. How is a chemical reaction energy? Its a process.

electrical energy = electricity ...
chemical energy = just think of it as ... chemical reactions evolve into products which release CHEMICAL ENERGY ( kenetic energy/heat) stuff like that . if it makes it easier for you..

[98.40_for_sure]

I am just having trouble identifying what the textbook means by "electrical energy" and "chemical energy"

Umm... no one seems to understand what you're asking...
Electrical and chemical energy are just different forms of energy? electrical is the shit you use for light bulbs and chemical energy is the energy produced from chemical reactions

haha sorry 99.5_forsure

but yeh hes right
sorry kenhung . i dont really understand what ur asking
but i hope what im saying is making some sence for you

[kenhung123]

Because apparently in electrolysis electrical energy is converted to chemical energy. I don't understand where this chemical energy is stored. Unless your looking it as chemical reactions produce electrons and in electrolysis electricity produce chemical reactions..

[98.40_for_sure]

The chemical energy is within the products. The point of electrolysis is to rewind the clock basically, because when discharging, the chemical energy is being used up, and when it's gone... you put it back in! via electrical energy. Then after its recharged, you use the chemical energy you made and the cycle goes on
