For a second order reaction, half-life concentration of reactants:

In a first order reaction, the concentration of the reactants is reduced to 25% in one hour. The half-life periof of the reactions is

In a first order reaction, the concentration of the reactants is reduced to 25% in one hour. The half-life periof of the reactions is

In the first order reaction, the concentration of the reactant is reduced to 12.5% in one hour. The half-life period of the reaction is:

A reaction is second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is: reduced to half ?

(A ) If in a zero order reaction, the concentration of the reactant is doubled, the half-life period is also doubled. (R ) For a zero order reaction, the rate of reaction is independent of initial concentration.

For a chemical reaction, if the concentration of the reactant a doubled, its half-life is halved. Determine the order of the reaction.

(A) 25% of the first order reaction will be completed in 50% of the half - life period. (R ) Half-life of first order reaction depends on concentration of reactant
