C
$\Delta H_{\text{reaction}}$
D
Exothermic Process

List - II

(A) - (II), (B) - (III), (C) - (IV), (D) - (I)

(A) - (II), (B) - (III), (C) - (I), (D) - (IV)

(A) - (II), (B) - (I), (C) - (III), (D) - (IV)

Answer and worked solution

Official answer: B

Match. Spontaneous: $\Delta G_{T,P}<0$ (II). $\Delta P=\Delta T=0$ : isothermal and isobaric (III). $\Delta H_{\rm reaction}$ : bond energies of reactants minus products (IV). Exothermic: $\Delta H<0$ (I).

(B)

Topics:Gibbs energy and spontaneity Bond enthalpy
