Identify the reaction order from each of the following rate constants

1.	Identify the reaction order from each of the following rate constants :(i) k = 2.3 x 10–5 L mol–1 s–1.(ii) k = 3 × 10–4 s–1
Answer» (i) L mol^–1 s^–1 = (mol L^–1) ^{1 – n} s^–1 1 = –1 + n n = 2 :. Reaction order = 2 (ii) s^–1 = (mol L^–1) ^{1 – n} s^–1 0 = 1 – n n = 1 :. Reaction order = 1

Identify the reaction order from each of the following rate constants :(i) k = 2.3 x 10–5 L mol–1 s–1.(ii) k = 3 × 10–4 s–1

Answer»

(i) L mol^–1 s^–1 = (mol L^–1) ^{1 – n} s^–1

1 = –1 + n

n = 2

:. Reaction order = 2

(ii) s^–1 = (mol L^–1) ^{1 – n} s^–1

0 = 1 – n

n = 1

:. Reaction order = 1
