Balance the equation and tell if it is spontaneous and Ecell

Balance the equation and tell if it is spontaneous and Ecell= .

AgCl(s) +NO(g)--> Ag(s) +Cl-(aq) +NO-3(aq)

Solution

3AgCl (s) + 3e- ------> 3Ag (s) + 3Cl- Eo = -0.22 V
NO + 2H2O -----> NO31- + 4H+ + 3e- Eo = +0.96 V
3AgCl + NO + 2H2O -----> 3Ag + NO31- + 3Cl- Eocell = +0.74 V (spontaneous)
