Determine the equilibrium constant, K, for the voltaic cell composed of the following
2 half reactions at 298 K.
Sn²+ (aq) + 2e
Mn²+ (aq) + 2e
Report your answer in the format 2.4E-3.
1.87E-36
Sn(s) Ecell = -0.136 V
Mn(s) E= -1.19 V
cell
Hint: Decide which half-reaction is the reduction reaction and which one is the
oxidation reaction by looking at Eº; the oxidation reaction should be reversed, and
Er will have the opposite sign.
