Question:medium
When the concentration of the reactant in a given reaction is halved and if the rate of reaction is halved, the order of the reaction is:
When the concentration of the reactant in a given reaction is halved and if the rate of reaction is halved, the order of the reaction is:
Show Hint
For first-order reactions:
\[
\text{Rate} \propto \text{Concentration}
\]
So halving concentration halves the rate.
