Question

For reaction aA → xP, when [A] = 2.2 mM, the rate was found to be 2.4mMs-. On reducing concentration of half, the rate changes to 0.6mMs- -. The order of reaction with reaspect to A is

Options

A.1.5
B.2.0
C.2.5
D.3.0

Solution

When the concentration of reactant is reduced to half its initial value, the rate is rediced half its initial value, the rate is reduced by = times
It means, rate ∝ [reactant]2
So, order of reaction = 2
