Paper: CSIR-NET December 2015 · Subject: Physical Chemistry · Chapter: Thermodynamics · Topic: Thermodynamics – General · Marks: 2 · Difficulty: Easy

$\Delta \mathrm{H}$ of a reaction is equal to slope of the plot of

(a)$\Delta \mathrm{G}$ vs $(1 / \mathrm{T})$

(b)$\Delta \mathrm{G}$ vs T

(c)$(\Delta \mathrm{G} / \mathrm{T})$ vs T

(d)$(\Delta \mathrm{G} / \mathrm{T})$ vs $(1 / \mathrm{T})$

Answer

Answer: D ✓ checked by 4AB · confidence high

Explanation

Gibbs–Helmholtz: ∂(ΔG/T)/∂(1/T) = ΔH, so ΔH is the slope of ΔG/T against 1/T.
