A first order reaction is completed 99% in 20 minutes at 300 K. What is the half-life period of the reaction at the same temperature?}

At 300 K a first order reaction is 50 % completed in 10 minutes. What is the rate constant value of the reaction at this temperature? \((\log 2 = 0.3)\)}

For the elementary reaction, \(M \to N\), the rate of disappearance of ‘M’ increases by a factor of 8 upon doubling the concentration of M. The order of the reaction with respect to M is}

The rate constant of a reaction at $400$ K and $500$ K are $0.04$ min$^{-1}$ and $0.08$ min$^{-1}$ respectively. The activation energy of the reaction is about \ ($2.303R=19$ J K$^{-1}$ mol$^{-1}$, $\log 2 = 0.3010$)

A reaction is third order with respect to a reactant. If the concentration of the reactant is doubled, the rate of reaction increased by

For chemical reaction M \(\rightarrow\) N, the rate becomes 8 times when the concentration of M doubles, find the order of reaction with respect to M?

Find the rate constant of a first order reaction A \(\rightarrow\) B reaction where \(\text{t}_{1/2} = 10 \text{ minutes}\) at \(300 \text{ K}\) is (Given log 2 = 0.3)

For a \(\text{I}^{\text{st}}\) order reaction, 99% complete in 20 minutes, then the \(\text{t}_{1/2}\) will be : (log2 = 0.3)
