Solution
The correct option is A zero order
as time increase the concentration of reactant decreases , as rate changes
but here rate is being constant with time so it does not depend on concentration
So rate =K[A]0
zero orderFor zero order reactions, the rate of the reaction does not change with time.
r=k[A]m Here m=0
as time increase the concentration of reactant decreases , as rate changes
but here rate is being constant with time so it does not depend on concentration
So rate =K[A]0
zero order
For zero order reactions, the rate of the reaction does not change with time.
r=k[A]m Here m=0
r=k[A]m Here m=0
