Question

In the Arrhenius equation,
$k=A{e}^{-E_A/\left(RT\right)}$
What does $k$ refer to:

• A. the temperature of the reaction.
• B. the activation energy of the reaction.
• C. the rate constant of the reaction.
• D. a constant factor dependent upon the reaction.

Answer 1

Answer: (C)

the rate constant of the reaction.

In Arrhenius equation, $K=A{.e}^{{-E}_a/RT}$

K=rate constant

$E_a$=activation energy.

T=temperature

R=universal gas constant

$\therefore$ K refers to the rate constant of the reaction.
