Question

In a first order reaction A----->B, if K is rate constant and initial concentration of the reactant A is 0.5 then the half life is​

Answer 1

Half life time = 0.693/k

Answer 2

The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally. The value of the rate constant is temperature dependent.
