At-14.4 °C the concentration equilibrium constant K 5.2x10 for a certain reaction. Here are some facts about the reaction: . The initial rate of the reaction is 14. mol - L .s If the reaction is run at constant pressure, 117. kJ/mol of heat are released. The net change in moles of gases is 2. O Yes Using these facts, can you calculate Kc at 23. °c?
