Question

In certain areas where coal is cheap, artificial gas is produced for house hold use by the 'water gas' reaction:
$ ext{C(s)} + ext{H}_2 ext{O(g)} o ext{H}_2 ext{(g)} + ext{CO(g)}$
Assume that coke is 100% carbon. Given $\Delta H_c ext{ (kcal/mol)}$ at $25^\circ ext{C}$: $ ext{H}_2 ext{(g)} = -68.0$; $ ext{CO(g)} = -68.0$; $ ext{C(s)} = -94.0$. Select the correct option(s):

Correct answer: A,B,C. 1.2 kg coke = 100 mol C. Heat from C = . 100 mol C produces 100 mol and 100 mol CO. Heat from water gas = . 1.2 kg water gas (mixture MW 30) = 40 mol + 40 mol CO. Heat = .
