Question

Which plot of ln k vs $\frac{1}{T}$ is consistent with Arrhenius equation?

• A.
• B.
• C.
• D.

Answer 1

Answer: (D)

Answer 2

1. The Arrhenius equation is: $\ln k = -\frac{E_a}{R} \times \frac{1}{T} + \ln A$

2. A plot of $\ln k$ vs $\frac{1}{T}$ yields a straight line with a negative slope ($-E_a/R$).

3. The graph is linear and decreases as $\frac{1}{T}$ increases.
