The units of reaction -rate and constant of a given reaction are the same. Find the order of the reaction.

Explanation

For a reaction , rate `= k ["concentration of reactant "]^(n)` . Where 'n' is order of the reaction and 'k' is its rate constant.
When n = 0 , rate = k , indicating that k has the same unit as the rate of reaction . Thus, for a zero order reaction , reaction -rate and rate constant have the same unit.
