Calculate K at 25°C for the reactions given below.
(a) Zn(s) + 2Ag+(aq) Zn2+(aq) + 2Ag(s)
(b) 2H2O2 2 H2O + O2
Given:
H2O2 + 2 H+ + 2e- 2 H2O ° = 1.78 V
O2 + 2 H+ + 2e- H2O2 ° = 0.68 V

nFEo = RT*ln K
(a) Zn(s) + 2Ag+(aq) Zn2+(aq) + 2Ag(s)
(b) 2H2O2 2 H2O + O2
Given:
H2O2 + 2 H+ + 2e- 2 H2O ° = 1.78 V
O2 + 2 H+ + 2e- H2O2 ° = 0.68 V
