ElectroChemistry Problem
« on: May 13, 2013, 05:21:29 PM »
I am having trouble with a question on a practice test. The question is asking
"Consider the cell Pt|H2|HCl(aq, 1.0M) || AgNO3 (aq, 1M) | Ag. If Delta So for every mole of hydrogen gas consumed in this reaction is 162J/mol-K and delta Ho is -106 kJ/mol, what is the cell potential at 350K?"
a. 0.88V
b. 0.84V
c. 0.80V
d.0.76V
e. 0.29V

I just really want to know the process of solving a question like this. The method's and the concepts basically.
Any help is welcomed, and I thank you in advance.

Start with: what quantity can you easily calculate from ΔH°, ΔS° and T?
