Question
At -9.12 °C the concentration equilibrium constant K,
=9.6 × 10
- 5
for a certain reaction.
Here are some facts about the reaction:
- 1
• The constant pressure molar heat capacity C = 2.33 J•mol · K .
If the reaction is run at constant pressure, 87.0 kJ/mol of heat are released.
• If the reaction is run at constant pressure, the volume increases by 11.%.
O Yes.
Ox10
Using these facts, can you calculate K, at -21. °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
-21. °C will be bigger or smaller than K. at -9.12 °C?
smaller.
No.
