Calculate E cell for the following reaction at 25deg celcius

[Biggins1]

Homework Statement

2 IO3−(aq) + 6 H+(aq) + 10 I−(aq) →6 I2(s) + 6 H2O(l)

I didn’t want to re-type all of this up but I uploaded of picture of my work for this problem. I was just wondering if I completed it correctly and if not if someone could guide me in the right direction. Thank you!

You might want to try balancing the reaction for starters, charge conservation and other details.
