Application

Postby Gabriel Ordonez 2K » Sun Mar 08, 2020 7:22 pm

What are the different ways in which we manipulate the Gibbs Free Energy Equation for Electrochemistry and/or combine/separate the equation with other appropriate equations for this unit? Can someone provide a list and example?

I can think of two main ones: G=-nFE and G=-RTlnQ

I think we will usually be using:
G=-nFE
G=-RTlnQ

A couple of ways you can manipulate Gibbs Free Energy is by using these two equations:

G=-nFE
G=-RTlnQ

You can make them equal each other, take the standards of them, and even switch the Q to K.

G=-nFE
G=-RTlnK
These are the 2 equations you'll use.

The three equations for delta G.
delta G= -nFE
delta G= -RTlnK
delta G= delta H - T*delta S

You can delta the top two delta G's together.
You can also set the second equation equal to the third equation and solving for the Vant Hoff Equation.

Also remember you can combine these equations for the vant hoff equation
