Hw problem 14.35

Postby Katrina_Domingo_3G » Wed Feb 08, 2017 4:37 pm

14.35 Determine the equilibrium constants for the following reactions:
b) In3+ (aq) U3+ (aq) yields In2+ (aq) U4+ (aq)

I dont understand why they used n=2 for the number of moles of electrons?
The half rxns that I got were:

In3+ + 1e- --> In2+
U3+ --> U4+ + 1e-

In the solutions manual, the half rxns were:
In3+ + 2e- --> In2+
U3+ --> U4+ + 1e-

Why did they add two electrons to the first half rxn?

This is a typo that is already in the solutions manual errors .pdf on the course website.
