\( 2A + B \rightarrow Product \) 

If the reactant ''B'' is in excess, the order reaction with respect to ''A'' in a given rate law \( Rate=k[A]^2[B] \) is MDCAT2016

For reaction a A → x P , when [A] = 2.2 mM the rate was found to be 2.4mM^-1 s^-1.On reducing concentration of A to half, the rate changes to 0.6mM^-1 s^-1.The order of reaction with respect to A is [AIIMS 2005]
