Question

The rate constant of any reaction increases linearly with increase in temperature. Explain.

Answer 1

This statement is incorrect.

The rate constant of a chemical reaction does not increase linearly with temperature. Instead, it increases exponentially with temperature, as explained by the Arrhenius equation.

The temperature dependence of the rate constant k is given by the Arrhenius equation:

\[\ce{k = Ae^{-E_a/(RT)}}\]

Where:

k = rate constant

A = frequency factor

E_a = activation energy

R = gas constant

T = absolute temperature (in Kelvin)
