Answer:
<h2>A
</h2>
Explanation:
The activation energy for the forward reaction is the amount of free energy that is required or must be added to the system to go from the energy level of the reactants of the reaction to the energy level of the transition state( transition from reactants to product).
We can say that it is the minimum amount of energy needed to start a chemical reaction
So the activation energy of a chemical reaction is the energy that initiates the reaction.
Enzymes increases the rate of a reaction by decreasing this activation energy.

I hope this helps :)
Glass breaks and shatter easily.
<span>Petroleum and biomass are burned in combustion reactions, which liberate energy stored in chemical bonds. This is chemical energy. In contrast, nuclear energy comes from the conversion of mass into energy when an nuclear reaction occurs. Geothermal energy comes directly from heat sources underground, with no chemical or nuclear reactions.</span>
