easy · MCQ · Q-38088C

The unit of the rate constant for a zero-order reaction is:

  1. A.s−1^{-1}
  2. B.mol L−1^{-1} s−1^{-1}Correct answer
  3. C.L mol−1^{-1} s−1^{-1}
  4. D.L2^{2} mol−2^{-2} s−1^{-1}

Solution

For a reaction of order nn, the unit of rate constant is (mol L−1^{-1})1−n^{1-n} s−1^{-1}. For zero-order (n=0n=0), the unit is mol L−1^{-1} s−1^{-1}.
