Q4 n-butane (n-C_Ho) is isomerized to i-butane (i-C-H10). A gas reactor has a feed of a molar flowrate of 300 mole/h at 150C. The feed composition is 90 mole% n-butane, 7 mole% i-C.H10 and the balance is HCI .The conversion is 40% and the product is at 180 C [25 marks] a) Calculate the standard heat of the reaction b) Calculate the required heat transfer (use heat of reaction method) (Ans: - 91.44 KJ/h)
