Chemistry - Chemical Kinetics Question with Solution | TestHub

The rates of chemical reactions are strongly affected by temperature. Arrhenius (1889) gave the following relation between rate constant and temperature:

$k=A{e}^{-E_a/RT}..\dots (i)$

This equation is called Arrhenius equation. The constant 'A' is called Arrhenius constant or pre-exponential factor. Logarithm of equation (i) is given as:

$lo{g}_{10}k=lo{g}_{10}A-\frac{E_a}{2.303RT}$ ....(ii)

The rate constant for a reaction is:

${\log }_{10}k({\sec }^{-1})=14-\frac{1.25\times 10^{4}K}{T}$ .....(iii)
