A first-order reaction was started with a decimolar solution of the reactant, `8` minutes and `20 `seconds later its concentration was found to `M//100`. So the rate of the raction is

A first order reaction was started with a decimolar solution of the reactant , 8 minutes 20 seconds later its concentration was found to be M/100. So the rate constant of the reaction is ___ .

A first order reaction was commenced with 0.2 M solution of the reactants. If the molarity of the solution falls to 0.02M after 100 minutes the rate constant of the reaction is

In a first order reaction, the concentration of the reactant is reduced to 1/8 of the initial concentration in 75 minutes at 298 K. What is the half-life period of the reaction in minutes ?

For a first order reaction, the rate of the reaction doubled as the concentration of the reactant is doubled.

For a first order reaction, the rate of the reaction doubled as the concentration of the reactant is doubled.

In a first order reaction,the initial conc.of the reactant was M/10 .After "8" minutes "20" seconds the conc.becomes M/100 . What is the rate constant?
