Question

According to Arrhenius equation, the rate constant of a chemical reaction is equal to ______.

Options

• `A e^(-E_a//RT)`

• `A e^(E_a//RT)`

• `A e^(-RT//E_a)`

• `A e^(RT//E_a)`

Answer 1

According to Arrhenius equation, the rate constant of a chemical reaction is equal to `bbunderline(A e^(-E_a//RT))`.

Explanation:

According to the Arrhenius equation, the rate constant k is given by:

`A e^(-E_a//RT)`

Where:

A = frequency factor (Arrhenius constant)

E_a = activation energy

R = gas constant

T = temperature in Kelvin

This equation shows how the rate constant increases with temperature and decreases with higher activation energy.
