Calculate the cell potential for a given electrochemical reaction where the half-cell reactions are:* Fe3+(aq) + e- → Fe2+(aq) E° = 0.77 V* Ag+(aq) + e- → Ag(s) E° = 0.80 VAssume 1.0 M solutions and standard state conditions. Determine whether the reaction is spontaneous or non-spontaneous under standard conditions.

A chemistry student is asked to determine the effect of temperature and pressure on the equilibrium of the reaction: 2NO2(g) ⇋ N2O4(g) using Le Chatelier’s principle. The initial concentration of NO2(g) is 0.5 mol/L and the reaction is carried out at 25°C. How will the equilibrium shift if the temperature is increased to 100°C and the pressure is decreased to 0.5 atm?
