1. What is the standard free energy change for the reaction H2 + 2 Ag+(aq) → 2 H+(aq) + 2 Ag(s)? The standard potentials are 2 H+ + 2 e- → H2 (0 V)Ag+ + e- → Ag (0.7994 V) Answer in units of kJ.
2. Consider two hypothetical metals, X and Y,which can exist as metal ions X2+ and Y3+,respectively. For these two metals, the standardreduction potentials areX2+ + 2 e- → X E0 = -0.850 VY3+ + 3 e- → Y E0 = 1.800 VCalculate Ecell for the reaction3 X(s) + 2 Y3+(0.130 M) →3 X2+(0.0170 M) + 2 Y(s).Answer in units of volts.
