WebApr 14, 2024 · So, are you saying for an exothermic reaction at higher temperature, that Keq decreases, while Keq/Q increases, because of the reduced effect of transferring … WebMar 16, 2024 · a. The reaction does occur spontaneously as the AgCl precipitates thereby removing Ag + and Cl-ions from solution and driving the reaction to the right.. b. The reaction is exothermic. In a spontaneous reaction the Gibb's free energy change is negative, but the entropy change is negative as a less disordered system is produced. WebFor a certain reaction, Keq = 15.5 at 300 K and the reaction is endothermic by 14.3 kJ/mol. What is Keq at 500 K? An exothermic reaction occurs with a Delta H of -95.6 kJ mol^-1. In this system, what value must the entropy exceed for the reaction to be spontaneous at 56 degrees C and P = 1 bar? In an endothermic reaction, _____. birth certificate 日本
