In a first order reaction, the concentration of the reactant is reduced from 0.6 mol `L^(-1)` to 0.2 mol `L^(-1)` in 5 minutes. Calculate the rate constant of the reaction.

Explanation

Substituting the values in the first order equation
`k=(2.303)/(t)"log"([R]_(0))/([R])`
`k=(2.303)/(5"min")xx"log"(0.6)/(0.2) or k=(2.303)/(5)xx log3`
or `k=(2.303)/(5)xx0.4771=0.2198`
