P6.35 In this problem, you calculate the error in assuming that A, H is independent of T for the reaction 2CuO (s) = 2Cu (s) + 02(g). The following data are given at 25"C: Compound CuO(s) Cu(s) Oz(g) A Ho(kJ mol ) -157 A-Go(kJ mol ! ) -130. Cpm(J K ' mol ]) 42.3 24.4 29.4 Kp( T/ ) a. From Equation (6.69) din Ky A He = R 72 -dT. Kp(T) To a good approximation, we can assume that the heat capacities are independent of temperature over a limited range in temperature, giving A, He(T) = A, He(7)) + ACp(T - 71) where ACp = EviCrm(i). By integrating Equation (6.69), show that A,He(TI) In Kp(7') = In Kp(7;) R + T X ACp ACp T + In R R T. b. Using the result from part (a), calculate the equilibrium pressure of oxygen over copper and CuO(s) at 1100. K. How is this value related to Kp for the reaction 2CuO(s) 2Cu(s) + Oz(g)? c. What value would you obtain if you assumed that AH were constant at its value for 298.15 K up to 1100. K
