List of top Chemistry Questions on Zero, first and second order kinetics

For a first order reaction, the time required for completion of \(75\%\) of the reaction is \(40\) minutes. The half-life of the reaction is:

A first-order reaction has a specific rate constant (\( k \)) equal to \( 2.303 \times 10^{-3} \text{ s}^{-1} \). Calculate the exact time required for the initial concentration of the reactant to be reduced to exactly \( \frac{1}{10} \)th of its original value.

99% of a first order reaction was completed in 32 minutes. When will 99.9% of the reaction complete?

\(t_{99.9%}\) with respect to \(t_{90%}\) for a first order reaction is:

Which of the following is not the graphical representation of first-order kinetics?
