Question

At-14.8 °C the pressure equilibrium constant Kp 9.5 x 10 for a certain reaction. Here are some facts about the reaction . Some of the reactants are liquids and solids .If the reaction is run at constant pressure, 149. kJ/mol of heat are absorbed. · If the reaction is run at constant pressure, the volume increases by 13,%. Yes. Using these facts, can you calculate Kp at -35. C? If you said yes, then enter your answer at right. Round it t 2 significant digits Yes, and K will be bigger If you said no, can you at least decide whether Kp at Yes, and Kp will be smaller 35. °C will be bigger or smaller than Kp at 14.8 °C?

Explanation / Answer

Part (i)

No

Part (ii)

-

Part (ii)

Yes, and Kp will be smaller.

Reason: Kp is directly related to temperature, i.e. as the temperature decreases the value of Kp will be smaller. Here, -35 oC < -14.8 oC
