The rate constant for a first order reaction is 60 (s)^(-1) .How much time will it take to reduce the initial concentration of the reactant to its `1 / 16th value?

The rate constant of a first order reaction is 231 xx 10^(-5)- s^(-1) How long will 4 g of this reactant reduce to 2 g?

The rate constant of a second order reaction is 5xx10^(-5)"mol^(-1)"lS^(-1) .When the equlibrium concentration of the reactant is 0.25 "mol"L^(-1) ,the value of the rate is

For a 1st order reaction, half life is 14 sec. The time required for the initial concentration to reduce to (1)(8) of its value is

In a first order reaction mathbf(A) rarr (B) if (k) is rate con stant and initial concentration of the reactant A. is 0.5 . M then the.half life is

The reaction A rarr X is a first order reaction which takes place in a vessel with initial concentration of A as 10 M. The rate constant for this reaction is 4.16 h^(-1) . In the presence of a catalyst, the reaction A rarr Y follows second-order kinetics and the rate constant is 0.2 min^(-1) M^(-1) . What should be the initial concentration of A in the presence of catalyst so that the value of t_(1//2) for both the reactions is the same?

80% of a first order reaction was completed in 70 min. How much it will take for 90% completion of a reaction?
