Options

  1. AA-III, B-II, C-IV, D-I
  2. BA-II, B-III, C-IV, D-I
  3. CA-III, B-II, C-I, D-IV
  4. DA-II, B-III, C-I, D-IV

Correct answer

D. A-II, B-III, C-I, D-IV

Step-by-step solution

For a zero-order reaction, the half-life is given by t_ 1/2 = [R]₀ 2k . A plot of t_ 1/2 versus [R]₀ is a straight line passing through the origin. Thus, A matches II. For a zero-order reaction, the rate is independent of the reactant concentration (Rate = k ). A plot of rate versus [R] is a horizontal line parallel to the concentration axis. Thus, B matches III. For a first-order reaction, the integrated rate equation is ₁₀[R] = -k 2.303 t + ₁₀[R]₀ . A plot of ₁₀[R] versus time is a straight line with a slope of -
