This question has Statement I and Statement II. Of four choices given after the Statements choose the one that best describes two statements Half life of a reactant following first order kinetics is independent of concentration. Statement-II: The time required to complete any definite fraction of the first order reaction is independent of the initial concentration.

At a given initial concentration of reactant , the half-life of a reaction is found to be 50min . If the initial concentration is quadrupled , then half-life of the reaction becomes 25min . The order of the reaction is -

When initial concentration of the reactant is doubled, the half-life period of a zero order reaction -

When initial concentration of the reactant is doubled, the half-life period of a zero order reaction-

Half - life of a first order reaction is 15 min . Calculate rate constant of the reaction and the time required to complete 80% of the reaction. If the initial concentration of the reactant is doubled , how long will it take to reach 50% completion ? Give reason.

How does the initial concentration of the reactant in a first order reaction very with time ?

In a zero -order reaction , initial concentration of the reactant is a and value of the constant is k . If the time required for the completion of the reaction is t and the value of its half-life t_(1//2) then-

t_(1//2) of a first order reaction is 15 min . Calculate the time for 80% completion of the reaction . If the initial concentration of the reactant is doubled , calculate the time taken for 80% completion of the reaction Give reasons.

What is the unit of rate constant of n^(th) order reaction?

For the reaction : aA+bBrarrcC , the rate law is , r=k[A]^(m)[B]^(n) . If the initial concentration of A and B are doubled, then find the ratio of the new initial rate to the original initial rate.
