# Calculate E cell for the following reaction at 25deg celcius

• Biggins1
In summary, the student calculated the E cell for the following reaction at 25 degrees Celsius. They looked it up in a handbook and found that the reaction has a \mathcal{E} of +1.679. They also found that one half of the reaction occurs in each of two cells and that the final result is an EMF.f

## Homework Statement

Calculate E cell for the following reaction at 25deg celcius

3 CU(s) + 2 MnO4-(aq) + 8 H+(aq) →2 MnO2(s) + 3 CU^2+(aq) + 4 H2O(l)

Given: [CU^2+] = 0.010M, [MnO4-] = 2.0M, [H+] = 1.0M

I’ve posted a picture of my work, if someone could just let me know if I answered the question correctly and if not guide me as to how to correctly complete the problem. Thank you!

You need to keep the homework template in place on homeworks please. Also welcome to PF.
I needed to review this material=I had it 40+ years ago in a chemistry sequence.
You didn't show all of the work.
