Which of the following statements about zero order reaction is not true

Options

  1. AIts unit is molL − 1 time − 1
  2. BThe graph between log (reactant) versus rate of reaction is a straight line
  3. CThe half life for zero order reaction is independent of initial concentration.
  4. DRate of reaction is independent of concentration of reactants

Correct answer

C. The half life for zero order reaction is independent of initial concentration.

Step-by-step solution

The unit for zero order reaction is molL − 1 time − 1 and the half life of zero order reaction is given by t 1 / 2 = [ A ] ∘ / 2 k , where [ A ] ∘ is initial concentration of reactant.
