Question

What is activation energy?

Answer 1

We know activation energy is characterized as the base measure of additional energy needed by a reacting particle to get changed over into product. It can likewise be depicted as the base measure of energy expected to initiate or give energy to atoms with the goal that they can go through a chemical reaction or change.

Complete step by step answer:
Let us discuss about the activation energy,
As we know that all particles have a specific least measure of energy. The energy can be as potential or kinetic as likely energy. At the point when atoms impact, the kinetic energy of the particles can be utilized to stretch, twist, and at last break bonds, prompting chemical reactions. In the event that atoms move too gradually with minimal active energy, or slam into inappropriate directions, they don't respond and just skip off one another. Notwithstanding, if the atoms are moving quick enough with an appropriate impact direction, to such an extent that the kinetic energy upon crash is more prominent than the base energy boundary, at that point a reaction happens. The base energy prerequisite that must be met for a chemical reaction to happen is known as the activation energy. It can be represented as${E_a}$.

Note: We have to remember that the Arrhenius condition gives the quantitative premise of the connection between the activation energy and the rate at which a response continues. From the condition, the enactment energy can be found through the equation,
$k = A{e^{\dfrac{ - {E_a}}{RT}}}$
Where A exponential constant
R is the universal gas constant
T is the total temperature
k is the reaction rate coefficient.
