< ✓ 11 Question 25 of 25 (1 point) | Question Attempt: 1 of 2 ✓ 12 ✓ 13 ✓ 14 Here are some facts about the reaction: ✓ 15 At -5.67 °C the concentration equilibrium constant K = 7.0 for a certain reaction. с • If the reaction is run at constant pressure, 101. kJ/mol of heat are absorbed. X 16 -1 1 • The constant pressure molar heat capacity C₂ = 2.23 J-mol K Р Using these facts, can you calculate Kat 9.4 °C? • If the reaction is run at constant pressure, the volume increases by 13.%. If you said yes, then enter your answer at right. Round it to 2 significant digits. If you said no, can you at least decide whether Kat 9.4 °C will be bigger or smaller than Kat -5.67 °C? O Yes. O No. 0 17 Yes, and K will be bigger. No. Yes, and K will be smaller.
