At -5.17 °C the concentration equilibrium constant K = 6.3 for a certain reaction. Here are some facts about the reaction: • The constant pressure molar heat capacity C = 2.82 J-mol K. • The initial rate of the reaction is 14. mol-L¹s¹. . If the reaction is run at constant pressure, 100. kJ/mol of heat are absorbed. Using these facts, can you calculate Kat-23. °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 Kat -23. °C will be bigger or smaller than Kat-5.17 °C? Yes. No. 0 Yes, and K will be bigger. Yes, and K will be smaller. No. X

Answer the following questions about this system: rise Under these conditions, will the pressure of NOCI tend to rise or fall? O fall ? Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fal by adding NO? Similarly, if you said the pressure of NOCI wil tend to fall, can that be changed to a tendency to rise by adding NO? O yes O no Ir you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits.
