At −12.6°C the concentration equilibrium constant Kc = 8.7 x 10^−5 for a certain reaction. Here are some facts about the reaction:

The initial rate of the reaction is 11. mol·L^−1s^−1
If the reaction is run at constant pressure, 85.0 kJ/mol of heat are absorbed.
If the reaction is run at constant pressure, the volume increases by 12.%
Using these facts, can you calculate Kc at −23°C?
If you said yes, then enter your answer at right. Round it to 2 significant digits.

If you said no, can you at least decide whether Kc at −23.°C will be bigger or smaller than Kc at −12.6°C?
