The addition of a catalyst during a chemical reaction alters which of the following quantities

The expression for rate constant of a first order chemical reaction is

The rate of a reaction is doubled when temperature increases by $10^\circ C$. If temperature is increased by $100^\circ C$, then rate of reaction will become

For a gaseous reaction, the units of rate of rate of reaction are

In Arrhenius equation, $k = A{e^{ - {E_a}/RT}};A$ may be called the rate constant at

A reaction has a rate constant 'k' at temperature T₁ and k' at T₂ (T₂ > T₁). If the activation energy is Ea, which expression correctly relates k, k', T₁, and T₂ according to the Arrhenius equation?

The minimum energy required for the reacting molecules to undergo reaction is :

A first-order reaction has a rate constant of $9.21 imes 10^{-3} \, s^{-1}$. How long will it take for the concentration of the reactant to decrease from $1.5 \, M$ to $0.3 \, M$?

For a reaction for which the activation energies of forward and reverse reactions are equal?

In Arrhenius plot intercept is equal to

The rate of a chemical reaction doubles for every 10\,^\circ C rise of temperature. If the temperature is raised by 50\,^\circ C, the rate of the reaction increases by about
