`ArarrB` at a specific temperature, the rate constant of the reaction is `2.8xx10^(-3)"mol"^(-1).L.s^(-1)` If the concentration of A is halved, what will be the rate of the reaction?

Text Solution

Verified by Experts

The rate constant indicates that the reaction is of the second order. If the rate of reaction at [A] concentration = r , then at `([A])/(2)` concentration, the reaction -rate would be `(r)/(4)`
