NEET Chemistry Chemical Kinetics Questions Solved

BOARD

A reaction is of second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is reduced to half? What is the unit of rate constant for such a reaction?

Rate = K[A]2 = Ka2

 If [A] =12a          Rate= Ka22 =14Ka2

  Rate =14th (one fourth of original rate)

The unit of rate constant is L mol-1 s-1 .
