Hi Guys,
Need help with this question. The question is in the attachment.
What do they mean faradays of charge? Is that just F? And I thought 1F=96500C/mol?
I'm confused. How will you solve them?
Thanks. All help will be really much appreciated.
The question is a little misleading. For this question, just pretend 1 F = 96500 C, even though it's not.
Just to confirm - are gas laws/relationships between factors (e.g. temp, pressure, mol) affecting gases, application of gases etc on the study design? Or do we just have to know how to use the gas formulus (PV = nRT?)
You should be able to work out the relationships from the ideal gas law, which was formulated to combine all of the factors together in one equation.
If a question on galvanic cells asks for the electrode/cathode/anode on a half cell where the electrode is aqueous, is it better to write the aqueous electrode or to just say an inert electrode?
Thanks
Electrodes are never aqueous though......they're always solid. They might be inert, like platinum, but they're never aqueous. Otherwise, you can't separate any products from the reactants if the reactions occur in solution.
Hey guys,
What are some reasons for why the experimental voltage of a galvanic cell is lower then the expected voltage shown on the electrochemical series?
Non-standard conditions, faulty voltmeter, extra resistance in the system, for starters.
