Chemistry - Thermochemistry Question with Solution | TestHub
A factory is producing methanol based on the reaction:
CO + 2H2 → CH3OH; ΔH = -120 R
Hydrogen and carbon monoxide are obtained by the reaction:
CH4 + H2O → CO + 3H2
Three units of factory, namely, reformer (for the production of H2 and CO), reactor (for the production of methanol from CO and H2) and separator (to separate CH3OH from CO and H2) are schematically shown in the figure:
The flow of methanol from Valve-3 is 600 mol/sec. The factory is so designed that 3/4 of the CO is converted to CH3OH. Assume that the reformer reaction goes to completion and R = 2 cal/K-mol.
Amount of energy released in methanol reactor in one minute is
Options:
Answer:
Solution:
Methanol formed in 1 min = 600×60 = 3.6×104 mol. Heat per mol = 120R = 240 cal = 0.24 kcal. Energy = 3.6×104×0.24 = 8640 kcal. This is option (c).
