Consider the given plots for a reaction obeying Arrhenius equation (): ( and are rate constant and activation energy, respectively)
- a
I is wrong but II is right
- b
Both I and II are wrong
- c
I is right but II is wrong
- d✓
Both I and II are correct
Both I and II are correct
Arrhenius equation: , so
Plot I — vs : As increases, increases (non-linearly, since the relationship is ). The curve is concave and increasing. Correct.
Plot II — vs : This gives a straight line with slope (negative slope). Correct.
Answer: Option (4) — Both I and II are correct
