1. A chemical reaction was conducted at several different temperatures (measured in K) and the equilibrium constant was measured at each one. Plotting the data on a graph with ln K on the y-axis and 1/T on the x-axis gives a linear plot with slope = -4594.6 and y-intercept = 13.6. What is ΔrH° (in kJ mol-1 ) and ΔrS° (in J mol-1 K -1 )?

2. Consider the galvanic cell:

Al (s) | Al3+ (aq, 0.018 mol L-1 ) || Fe2+ (aq, 0.85 mol L-1 ) | Fe (s)

a) Write out the overall reaction taking place in this cell.

b) Calculate E°cell for this cell at 298 K to two decimal places.

c) Calculate Ecell for this cell at 298 K to two decimal places.

d) If this cell is allowed to operate, will Ecell increase, decrease or remain constant over time? Briefly explain.

3. For the following reaction at 500 K:
