We are asked to calculate the equilibrium constant for each of the following reaction at 298 K


10Br- (aq) + 2MnO4 - (aq) + 16H+  (aq) →  2Mn2 +   (aq) + 8H2 O (l) + 5Br2 (l)


We can solve this using the formula below:

E°cell = 0.0592 Vnlog K

Ecell = cell potential under non-standard conditions
cell = standard cell potential
n = number of e- transferred
K = equilibrium constant = [products]/[reactants]
