Consider the reaction

2 SO2(g) + O2(g) in equilibrium with 2 SO3(g) .

At 25°C delta H° = -197.78 kJ and delta S° = -187.95 J/K. Using this information, calculate the equilibrium constant for the reaction at -32°C. (R = 8.314 J/K)

Enter your answer using TWO significant figures. You may use scientific notation with an "e" if necessary (e.g. 1.2e34).
