At -18.0 °C the pressure equilibrium constant K = 8.1 for a certain reaction. Here are some facts about the reaction: • The constant pressure molar heat capacity C = 1.84 J-mol ¹K¯¹. . The reaction' is exothermic. • The net change in moles of gases is -2. Using these facts, can you calculate Kat-40. °C? 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 K at -40. °C will be bigger or smaller than K, at -18.0 °C? O Yes. O No. 0 Yes, and K will be bigger. Yes, and K will be smaller. No.
