Quantitative thermal analysis has been suggested as a technique for monitoring the composition of a binary gas stream. To illustrate the principle, do one of the following problems.
(a) A methane/ethane gas mixture is heated from 25 to 250(C at 1(atm) in a steady- flow process. If Q = 11, 500 J mol-1, what is the composition of the mixture?
(b) A benzene/cyclohexane gas mixture is heated from 100 to 400(C at 1(atm) in a steady-flow process. If Q = 54,000 J mol-1, what is the composition of the mixture?
(c) A toluene/ethylbenzene gas mixture is heated from 150 to 250(C at 1(atm) in a steady-flow process. If Q = 17,500 J mol-1. What is the composition of the mixture?
