Question

The following reaction at 25°C produces 74.6 kJ of heat and 24.1 kJ of heat is lost to the surroundings.How much energy is available to do work? C(s)+ 2H₂(g)→ CH₄(g)

Quizplus · Accepted Answer

The amount of energy available to do work can be calculated using the equation:
Energy available = heat produced - heat lost to surroundings

Energy available = 74.6 kJ - 24.1 kJ
Energy available = 50.5 kJ

Therefore, the correct choice is C.
