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, 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, 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, what is the composition of the mixture?
