According to the transition state theory, the plot with slope equal to $\frac{\Delta H^{\ddagger}}{R}$ is
(a)$\ln k$ vs. $T$
(b)$\ln \dfrac{k}{T}$ vs $T$
(c)$\ln \dfrac{k}{T}$ vs $\dfrac{1}{T}$
(d)$\ln k$ vs. $\dfrac{1}{T}$
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
Eyring: ln(k/T) = ln(k_B/h) + ΔS‡/R − ΔH‡/RT, so ln(k/T) vs 1/T has slope −ΔH‡/R (c).
