Question
At - 5.55 °C the concentration equilibrium constant K¸ = 7.8 for a certain reaction.
Here are some facts about the reaction:
• If the reaction is run at constant pressure, 61.0 kJ/mol of heat are released.
• The constant pressure molar heat capacity C, = 1.60 J -mol¯. K.
• If the reaction is run at constant pressure, the volume increases by 15.%.
Yes.
Using these facts, can you calculate K, at -26. °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
-26. °C will be bigger or smaller than K, at -5.55 °C?
smaller.
No.
