Consider the following in respect of zero order reaction I. (t_ 1 / 2 ) is directly proportional to the initial concentration II. Time taken for the completion of the reaction is twice its ( t _ 1 / 2 ) III. Concentration of the reactant decreases linearly with time Which of the statements given above are correct?

Options

  1. AI & II only
  2. BI & III only
  3. CII & III only
  4. DI, II & III

Correct answer

D. I, II & III

Step-by-step solution

For zero order (i) (t_ 1 / 2 = a 2 ~K ) (t_ 1 / 2 a ) ( aligned & (ii) x=K t & K= x t t_ 1 / 2 = a 2 x t & t_ 1 / 2 a t 2 x & t 2 t_ 1 / 2 a x aligned ) (iii) concentration decreases with time.
