Practice Problem: Cell Potential, Equilibrium Constants, and Free Energy Change
Mercy me, how are cell potential, equilibrium constants, and free energy change all related? By a few different equations, that's how. See if you can solve for these values given some data!

Practice Problem: Galvanic Cells and Reduction Potential
We've learned about electrochemistry and electrochemical cells, especially galvanic or voltaic cells. And we learned about standard reduction potentials associated with a variety of substances. Given some data, can you calculate the cell...
