True or False : If `[A]_0` is the initial concentration of a reactant following first order reaction, then after three half lives its concentration becomes `([A]_0)/3^2` .

If a is the initial concentration of the rectant, the half life period of the reaction of n^(th) order is inversely proportional to :

When initial concentration of a reactant is doubled in a reaction, its half-life period is not affected. The order of the reaction is

If the initial concentration of the reactant is doubled, the time for half reaction is also doubled. Then order of the reaction is

If a is the initial concentration of the reactant what is the time required for 100 % completion of a zero order reaction

In a first-order reaction A rarr B, if k is rate constant and initial concentration of the reactant A is 0.5 M, then the half-life is :

In a reaction when the concentration of reactants is double, the rate of reaction becomes 8 times. What is order ofreaction ?

The integrated rate equations can be fitted with kinetic data to determine the order of a reaction. The integrated rate equations for zero, first and second order reactions are : Zero order : [Al =-kt+ [A]_0 First order : log [A] = -(kt)/2.303 + log [A]_0 Second order : 1/([A])=kt+1/[A]_0 These equations can also be used to calculate the halt life periods of different reactions, which give the time during which the concentration of a reactant is reduced to half of its initial concentration, i.e, at time t_(1//2), [A] = [A]_0//2 Answer the following (1 to 5) question : For a second order reaction, the correct plot of t_(1//2) vs. 1//[A]_0 is

The half life period is

The t_(1//2) of a reaction is halved as the initial concentration’ the reactant is doubled. What is the order of the reaction?
