Which of the following statements about Kp is/are true? It equals -Qpat equilibrium it equals exp(42") It is a pressure-dependent quantity It is a temperature-dependent quantity (a), (b), and (d) All of the above. At 300 K (for which RT -0.6 kcal mol?) the equilibrium constant for the 1 bar gas-phase isomerization of cis-1.2- difluoroethylene to trans-1.2-difluoroethylene is Kp 1.00. By how much do the molar free energies of formation of the cis and trans isomers differ at 300 K? Okcal mol-1 0.6 kcal mol-1 14 kcal mol-1 6 kcal mol-1 0.6 kcal mol-1 It depends on the number of moles initial compound
