NEET Chemistry Chemical Kinetics Questions Solved

BOARD

What do understand by the rate law and rate constant of a reaction? Identify the order of a reaction if the units of its rate constant are:

(i) L-1 mol s-1      (ii) L mol-1 s-1

The rate of reaction is found to depend on α concentration of term of reactant A and β concentration term of reactant  B

Then Rate of reaction  [A]α[B]β

or  Rate = K[A]α[B]β

This expression is called Rate law.

    'K' in this expression is called Rate constant.

Rate constant's unit:

(i) Unit= L-1 mol s-1  Zero order reaction

(ii) Unit=L mol-1 s-1  Second order reaction.
