Correct Option (B) mol lit–1 sec–1
Explanation:
If the amount of products formed which is 10%, 20% and 30% is plotted against time i.e., 1 hr, 2 hr and 3 hr respectively, it is a straight line passing through the origin.
∴ it is a zero order reaction where x = kt ⇒ x/t =k
∴ dimensions of k = moles lit–1 sec–1
