For the following graphs, Choose from the options given below, the correct one regarding order of reaction is :

Options

  1. A(b) zero order (c) and (e) First order
  2. B(a) and (b) Zero order (e) First order
  3. C(b) and (d) Zero order (e) First order
  4. D(a) and (b) Zero order (c) and (e) First order

Correct answer

B. (a) and (b) Zero order (e) First order

Step-by-step solution

For zero order reaction's rate = K Reactant 0 ⇒ r = k t 1 / 2 = A 0 2 K for zero order For first order reaction → r = K [Concentration] Reactant concentration after time t → C t = C 0 e - kt
