List of top Chemistry Questions on Rate of a Chemical Reaction asked in AIIMS

: A catalyst increases the rate of a reaction. : In presence of a catalyst, the activation energy of the reaction decreases.

At a certain temperature, the first order rate constant, $k_{1}$ is found to be smaller than the second order rate constant, $k_{2}$. If the energy of activation, $E_{1}$ of the first order reaction is greater than energy of activation, $E_{2}$ of the second order reaction then with increase in temperature

A sample of $0.42 \,mg \,{ }^{233} UF _{6}$ shows an activity of $9.88 \times 10^{4}$ count per second. Its $t_{1 / 2}$ is

The temperature dependence of rate constant $(k)$ of a chemical reaction is written in terms of Arrhenius equation $k=A e^{-E_{\alpha} / R T}$. Activation energy $\left(E_{a}\right)$ of the reaction can be calculated by ploting

Rate determining step in nitration of benzene is
