Chapter 18, Problem 53GQ

About 5 billion kilograms of benzene, C₆H₆, are made each year. Benzene is used as a starting material for many other compounds and as a solvent (although it is also a carcinogen, and its use is restricted). One compound that can be made from benzene is cyclohexane, C₆H₁₂.

C₆H₆(ℓ) + 3 H₂(g) → C₆H₁₂(ℓ)

Δ_rH° = −206.7 kJ/mol-rxn;

Δ_rS° = −361.5 J/K · mol-rxn

Is this reaction predicted to be product-favored at equilibrium at 25 °C? Is the reaction enthalpy- or entropy-driven?
