Answer:
35 KJ.
Explanation:
The activation energy is the minimum energy that must be overcome for a reaction to take place.
In the diagram given above, the activation energy lies between the energy of the reactants and that at the peak.
Thus we can calculate the activation energy as follow:
Energy of reactants = 30 KJ
Energy at the peak = 65 KJ
Activation energy =..?
Activation energy = Energy at the peak – Energy of reactants
Activation energy = 65 – 30
Activation energy = 35 KJ
Therefore, the activation energy of th reaction is 35 KJ

A thermodynamically-controlled process describes a reaction that the most stable or more stable of two products is formed.
<h3>What is a thermodynamically-controlled process?</h3>
A thermodynamically-controlled process is a reaction in which the ratio of the product formed is determined by the relative stability of the products.
Thermodynamic control ensures that the most stable or more stable of two products is formed.
Therefore, a thermodynamically-controlled process describes a reaction that the most stable or more stable of two products is formed.

The atom is the smallest object that retains the properties of an element.
Atoms are composed of electrons and a nucleus.
The nucleus contains protons and neutrons.
All atoms are electrically neutral, because every atom has an equal number of electrons and protons.
