Amount of energy released in methanol reactor in one minute is — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Enthalpy change ΔH = -100 R per mole $CH_3OH$. Moles of $CH_3OH$ produced per second = 1000. Heat released per second = 1000 mol/sec × 100 R = 1000 × 100 × 2 cal/sec (taking R = 2.0 cal/K-mol) = 200,000 cal/sec = 200 kcal/sec. Heat released in 1 minute (60 seconds) = 200 kcal/sec × 60 sec = 12,000 kcal.
