Assertion (A) : The order of a reaction may be defined as the sum of the powers to which the concentration terms are raised in order to determine the rate of reaction gives the total order of reactions. Reason (R) : The number of molecules whose concentrations determine the ratio of reaction at a given temperature is called order to the reaction.

In a chemical reaction, rate of a chemical reaction increases with temperature. The reason is due to

The half-life period of a first-order chemical reaction is 6.93 min . The time required for the completion of 99% of the chemical reaction will be (log 2 = 0.301)

The half life period of a first order chemical reaction is 16.93 minutes. Time required for the completion of 99% of the chemical reaction will be ("log 2"=0.301) :

The speed of a chemical reaction depends on the catalyst used in the chemical reaction. True/False

The speed of a chemical reaction depends on the catalyst used in the chemical reaction.
