Question
At -9.63 °C the concentration equilibrium constant K = 7.0 for a certain reaction.
Here are some facts about the reaction:
1
• The constant pressure molar heat capacity C. = 1.49 J-mol
K
• Some of the reactants are liquids and solids.
• If the reaction is run at constant pressure, 100. kJ mol of heat are absorbed.
U Yes.
x1Q
Using these facts, can you calculate K, at 10. °C?
No.
If you said yes, then enter your answer at right. Round it to
2 significant digits.
Yes, and K, will be
bigger.
If you said no, can you at least decide whether K at
Yes, and K, will be
10. °C will be bigger or smaller than K, at -9.63 °C?
smaller.
O No.
