In a first order reaction, the reactant decomposes 25% of its initial concentration in 40 minutes. What is the value of rate constant of the reaction? (Given: $\log 3 = 0.4771$, $\log 4 = 0.6021$)

In a first order reaction, the concentration of the reactant is reduced from \(0.6\ \text{mol L}^{-1}\) to \(0.2\ \text{mol L}^{-1}\) in \(5\) min. What is the rate constant of the reaction? \((\log 3=0.4771)\)

\(A \rightarrow\) products, is a first order reaction. The time required to decompose \(A\) to half its initial amount is \(60\) minutes. The rate constant of the reaction \((in\ s^{-1})\) is

For the reaction \[ CH_3CO_2C_2H_5+H_2O \rightarrow CH_3CO_2H+C_2H_5OH \] Rate is given by \[ \text{Rate}=k[H_2O][CH_3CO_2C_2H_5] \] The initial concentrations of ethyl acetate and water are \(0.001\,M\) and \(2\,M\) respectively. The value of rate constant, \(k\), of the reaction, if \(99\%\) of ethyl acetate is hydrolyzed in \(10\) seconds is
