This is simply because when the activation energy is lowered, the reactant molecules collide more frequently and with greater energy per collision.
In Science, an activation energy can be defined as the minimum quantity of energy that must be provided for reacting chemical elements or molecules, in order to enable them undergo a chemical reaction.
This ultimately implies that, the rate of any chemical reaction would be faster when its activation energy is lowered, decreased, or reduced. Â Generally, an enzyme speeds up or catalyzes the rate of a chemical reaction by lowering its activation energy.
With reference to the time and temperature data collected for this chemical reaction, when the activation energy is lowered, the reactant molecules collide more frequently and with greater energy per collision.
