1. What is the unit of rate constant for first order reaction?

Ans. Sec or minute

1. What is activated complex?

Ans. It is the unstable transition state of the reactant with highest energy equal to threshold energy.

1. What is zero order reaction ?

Ans. The reaction in which rate of reaction is independent of concentration of the reactant is called as
zero order reaction.
e.g. H2 +Cl 2HC1

1. What is the order of the reaction given below? 2N2O5→ 2N2O4 +0

Ans. It is a Ist order reaction.
