Question
![At -14.9 °C the concentration equilibrium constant K = 7.8 x 10° for a certain reaction.
Here are some facts about the reaction:
. If the reaction is run at constant pressure, the volume increases by 10.%.
• The constant pressure molar heat capacity C= 1.21 J-mol¹ K¹.
• If the reaction is run at constant pressure, 123. kJ/mol of heat are released.
Using these facts, can you calculate Kat -6.2 °C?
If you said yes, then enter your answer at right. Round it to
