A stream of benzene vapor is heated from 123.7C to 150.8C in a continuous process at constant pressure. Use the polynomial expression below for the heat capacity to determine the change in specific enthalpy of benzene in the process. Cp kJ/(molK) = a + bT + cT? + dT3 with T in C and = a a = 74.06 x 10-3kJ/(mol:K) b= 32.95 x 10-5 kJ/(mol:K2) C = -25.20 x 10-8 kJ/(mol:K3) d= 77.57 x 10-12 kJ/(mol-K4) A H i kJ/mol
