(Q91) What is the value of the equilibrium constant (Keq) when the following reaction occurs at 25°C? Sn4+ (aq) + Zn (s) ---> > Sn²+ (aq) + Zn²+ (aq) The reduction potentials for the two half-reactions involved are: Sn4+ + 2 e---> Sn²+ (E°RED) = 0.15 V Zn²+ + 2 e---> Zn (s) (E°Red) = -0.76 V O 2.24 x 1013 4.06 x 1020 O 2.47 x 10-21 O 5.54 x 1030 O 2.35 x 1015
