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.
This solution answers two questions in the topic of physical chemistry. The expert explains how to determine standard free energy change in a provided reaction and describes any electrochemical reactions that would occur.
