Half life

For a certain...

Question

For a certain reaction involving single reactant it is found that [A]_o(t_1/2)^1/2remain constant. Where [A_o] is the initial concentration of the reactant and t_1/2 is the half life period.The order of the reaction is :-

a. 1

b. 0

c. 2

d. 3

Solution

as we know the half life time period of a second order equation is given by

here you can easily see that product of intial concentration and t1/2 is constant so from here you can easily say that the asked reaction is 2nd order
