N-Butane is converted to isobutane in a continuous isomerization reactor that operates isothermally at 149 ◦C. The feed to the reactor contains 93 mole% n-butane, 5% isobutane, and 2% HCI at 149 ◦C, and a 40% conversion of n-butane is achieved.

(a) Taking a basis of 1 mol of feed gas, calculate the moles of each component of the feed and product mixtures and the extent of reaction, ξ (mol).
(b) Calculate the standard heat of the isomerization reaction (kJ/mol). Then, taking the feed and product species at 25 ◦C as references, prepare an inlet-outlet enthalpy table and calculate and fill in the component amounts (mol) and specific enthalpies (kJ/mol).
(c) Calculate the required rate of heat transfer (kJ) to or from the reactor (state which it is). Then determine the required heat transfer rate (kW) for a reactor feed of 325 mol/h.
(d) Use your calculated results to determine the heat of the isomerization reaction at 149 ◦C, hr◦ (149 ◦C) (kJ/mol).
