# Rate of reaction can be expressed by Arrhenius equation as $k=Ae^{\large\frac{-E_a}{RT}}$.Select the correct statement

$\begin{array}{1 1}(a)\;k\;is\;equation\;constant\\(b)\;A\;is\;absorbtion\;factor\\(c)\;R\;is\;Rydberg's\;constant\\(d)\;E\;represents\;energy\;of\;activation\end{array}$

Answer: E represents energy of activation.
Arrhenius' equation gives the dependence of the rate constant k of a chemical reaction on the absolute temperature T (in kelvin), where A is the pre-exponential factor (or simply the prefactor), E_a is the activation energy, and R is the Universal gas constant:
$\quad$ By Arrhenius equation, $k=Ae^{\large\frac{-E_a}{RT}}$
