For a reaction: A ⇌ B, carried out at 27°C, the ratio of equilibrium concentrations of product to reactant changes by a factor of e² for every
Options:
Answer:
D
Solution:
K = e^(−ΔG°/RT), so Δ ln K = +2 needs Δ(ΔG°) = −2RT = −2 × 2 × 300 = −1200 cal = −1.2 kcal, i.e. a 1.2 kcal fall in ΔG°. Matches (d).
