__________ is the sequence of simple steps proposed in theory to explain how an overall reaction takes place.

_________ can be sham on the basis of the kinetic theory of gases that the number of collisions between molecules possessing greater than the activation energy, Ea, is proportional to the factor exp (- Ea / RT).

______ of a reaction is given by the total number of molecules of the reactants taking part in the reaction.

The molecularity of a reaction in which only one molecule of the reactant is involved is 1, such a reaction is said to be ___________.

According to ________ the rate of chemical reaction is directly proportional to the product of the concentration of reacting substances each when raised to the appropriate power.

______ is the time of a reaction takes to proceed to the half stage of its completion.

A substance that slows down a reaction is called a _________ catalyst.

____________ is a Substance which changes the rate of a chemical reaction remaining unchanged itself chemically and quantitatively.

_______ of a reaction is obtained by dividing the change in concentration of any reactants or products by time interval during which the change occurs.

According to the theory of ________ the catalyst undergoes a chemical change by reaction with a reactant, either in the rate determining step or in an earlier rapid step.
