The rate constant of a first order reaction is 1.54×10^(−3)sec^(−1) . Calculate its half life period.

The rate constant of first order reaction is 10^(-2)"min"^(-1) . The half-life period of reaction is

The rate of constant for first reaction is 0.0005" min"^(-1) . Calculate its half life.

The specific reaction rate of a first order reaction is 0.347 times 10^–3 sec^–1 . The half life period of the reaction will be :

The specific rate constant for a first order reaction is 1 times 10^–3 sec^–1 . If the initial concentration of the reactant is 0.1 mole per litre the rate (in mol l^-1 sec^-1 ) is:

If the half-life period for a first order reaction is 69.3 seconds, what is the value of its rate constant ?

If the half life period for a first order reaction is 69*3 seconds, what is the value of its rate constant ?

A : The rate constant of first order reaction is used to calculate population if growth rate is given. R : The rate constant is independent of concentration for first order reaction.
