In a zero-order reaction, if the initial concentration of the reactant is doubled, the time required for half the reactant to be consumed

In a reaction, the time required to complete half of the reaction was found to increase 16 times when the initial concentration of the reactant was reduced to 1/4th. What is the order of the reaction?

For a first order reaction, if ‘a’ is the initial concentration of reactant, then the half life time is

For a first order reaction half life is 14 sec. The time required for the initial concentration to reduce 1/8 of the value is

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 of such a reaction ?

Assertion. Half-life of a reaction is independent of the initial concentration of the reactant. Reason. Half-life of a reaction is independent of the order of reaction.

The half life period of a reaction is halved as the initial concentration of the reactants is doubled. The order of reaction is:
