The difference between heats of reaction at constant presure and at costant volume for the reaction :
2C 6 H 6 ( λ ) + 15O 2 (g) ⎯→ 12CO 2 (g) + 6H 2 O ( λ ) at 25ºC in kJ is :
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(– 7.432 kJ )
Sol. Δ H = Δ U + Δ nRT
Δ H – Δ U = – 3RT
= – 3 × 8.314 × 298 = – 7432 J = – 7.432 kJ
