n-Butane is converted to isobutane in a continuous isomerization reactor that operates isothermally at 175 °C. The feed to the reactor contains 83 mole% n-butane vapor, 15% isobutane vapor, and 2% HCl vapor at 175 °C, and a 50% conversion of n-butane is achieved. Assuming a basis of 1 mol of feed gas, calculate the amount of heat transfer to/from the reactor (kJ). The heat capacity for n-butane is 148.66 J/mol K and that for isobutane is 149.24 J/mol K. Use a reference state of 25 °C and 1 atm.
