Match the following:
Column–I | Column–II | ||
(a) | A + B C + D r = k1 [A] [B] | (p) | Unit of rate constant possess concentration unit |
(b) | A + B C + D r = k2 [A] [B]º | (q) | Rate constant for the reaction of both the reactants are equal |
(c) | A + B C + D r = k3 [A]º [B]º | (r) | Rate of consumption of at least one of the reactants is equal to rate of production of at least one of the products |
(d) | 2A + B 2C + 3D (s) r = k3 [A]º [B]º | (s) | If both reactants are taken in stoichiometric ratio, half life for both reactants are equal. |

p, q, r, s ; q, r, s ; p, q, r, s ; p, r, s
Sol. r = k [A] [B]
i.e. II nd order reaction
unit of k = mol –1 lt time –1
= 
= k [A] [B]
= 
(t 1/2 ) A = (t 1/2 ) B if A and B are taken in stoichiometric ratio.
A + B ⎯→ C + D
r = k 2 [B]º[A] = k 2 [A]
unit of k = time –1 does not have concentration unit.
= 
= k 2 [A]
= 
A + B ⎯→ C + D
r = k 3 [A]º [B]º
unit of k = mole litre –1 time –1
= 
= k 3
= 
2 A + B ⎯→ 2 C + 3D
r = K 3 [A]º [B]º
unit of K = mol lt –1 time –1
= 
⇒ 
=
