Question

In the first order reaction, 75% of the reactant disappeared in 1.388 h. Calculate the rate constant of the reaction

Answer 1

the answer is 0.75 s-1

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.
