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 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

The rate of the reaction is proportional to the concentration of the reactant. Hydrogenation of ethene results in the formation of ethane. The rate constant, k for the reaction was found to be 2.5xx10^(-15)s^(-1) . The concentration of the reactant reduces to one-third of the initial concentration in 5 minutes. Q. The rate constant of the reaction after 5 minutes is:

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?

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