    1. The Standard free energy change for the following reaction is -33.2 kJ/mol and the equilibrium constant Kp=6.59x105 at 25 C.
    N2(g) + 3H2 (g) <- -> 2NH3 (g)
    In a certain experiment, the initial pressures are P(H2)=0.25 atm, P(N2)= 0.87 atm and P(NH3)=12.9 atm. Calculate Delta G for the reaction at these pressures and predict the direction of reaction.

    2. Describe any electrochemical reactions(s) that would occur if molecular bromine (Br2) is added to a solution containing Cl- and I-. Assume all species are in their standard states in this solution.
