The specific rate constant of a first-order reaction depends on .......

The reaction rate at a given temperature becomes slower,then

The slope of the Arrhenius plot $(\ln k \, vs \, \frac{1}{T})$ of a first-order reaction is $-5 \times 10^{3} \, K$. The value of $E_{a}$ of the reaction is: (in $kJ \, mol^{-1}$)
$[\text{Given } R = 8.314 \, J \, K^{-1} \, mol^{-1}]$

Thermodynamic feasibility of the reaction alone cannot decide the rate of the reaction. Explain with the help of one example.

Which one of the following does not represent the Arrhenius equation?

Catalysts are used to increase the rate of a chemical reaction. Because it
