14.9

Postby Kyra LeRoy 1E » Sun Feb 18, 2018 3:14 pm

For all of the answers, I got my answers in Joules, but the solutions manual answers are in J/mol. Is there a reason for this, & will there be a difference between the two on the test?

When solving for ∆G˚ you should be getting your answers in J/mol because the Coulombs in Faraday's constant and voltage will cancel out. Voltage is J/Coulomb while Faraday's constant is in Coulomb/mol, multiplying them together will leave you with the J/mol.

It helps to write out all your units when you're doing a problem so you can see what cancels out for your final answer.
