Q121 · CSIR NET Chemistry, December 2015
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.
