The unit of second order reaction rate constant is
Options
(a) L⁻¹ mol s⁻¹
(b) L² mol⁻² s⁻¹
(c) L mol⁻¹ s⁻¹
(d) s⁻¹
Correct Answer:
L mol⁻¹ s⁻¹
Explanation:
For a second order reaction, -.d[A]/dt = k[A]². ⇒ K = -d[A] / dt ⨯ 1/ [A]² = 1 / s mol L⁻¹. So unit of K for second order reaction is L mol⁻¹ s⁻¹.
