Question

For complete combustion of ethane, C2H4(g) + 3O2(g) 2CO2(g) + 2H2O(l) the amount of heat produced as measured in bomb calorimeter is 1406 KJ mol–1 at 300K. The minimum value of TS needed to reach equilibrium is (–) __________ KJ. (Nearest integer) Given : R = 8.3 JK–1 mol–1

Prashant Kotian · Accepted Answer

Correct answer: .. For equilibrium G = 0    H - TS = 0    TS = H = E + ng RT H = 1406 + [–2] × 8.314 × 10–3 × 300 = 1401 kJ/mol
