You scared the crap out of me.

dw me too haha
Okay all the ambiguous MC out of the way. What did people get for 3)ii

What happens if ammonia is low or high? i was just like wtf?

[mirra250]

What did people get for 19? Did we get A?

I did D.. only because it was the last answer I cancelled out. I swear they are all wrong!!

[andy456]

i got 19 C reactants are not stored in a fuel cell....

I concur.... this one tripped me up because before the exam i read the fuel cells need reactants to be continuously pumped into the system

i know wtf! i just did that if it's too low a greater proportion of CO will be released, and if too high a greater proportion of NH3 will be released

[Xavier1234]

pretty sure 19 was A.

Yayyer. =]
I thought so when I read that.

[happycat]

I thought it was easy. Did the M/C section quicker than I expected. I got stumped on a few of those S/A question though

[Blackrat]

I said 4 a and 5 c )=

I got that.
For Q7 i said C, cause it had the most particles
and for Q8 i said A
Q 11, B
but...  oh god I hope I'm right  
and Q3 I said D, but i guessed that one

[mirra250]

i got 19 C reactants are not stored in a fuel cell....

C is untrue (just like all of the answers, they stuffed up).
C stated that the electrons went from the reductant to the anode. The electrons go to the CATHODE, never to the anode

[Studyinghard]

I thoguht it was a limiting/excess question. So i said if it was too low the NO would get released into the atmosphere but if it was too high then it would all get converted.

[Whatlol]

I said 19 A

You have more nitrogen oxide released then you have nitrogen and water if ammonia is low. The reverse happens when ammonia is high.

[mostafa1002]

pretty sure 19 was A.

reactants are not stored in a fuel cell....they have to be continuously supplied...
