The potential energy of the reactants from the energy profile diagram shown in the question is +200 KJ (option A)
How to determine the potential energy of the reactant?
Energy profile diagrams is a chart showing the starting energy of reaction as they proceed through the activation complex to arrive at the products
The energy of the reactants in an energy profile diagram is determined by observing the energy of the starting point (i.e the left side of the diagram)
With the above information, we can determine the potential energy of the reactants. This is shown below:
- Starting energy from diagram = 200 KJ
- Potential energy of reactant =?
Potential energy of reactant = Starting energy from diagram
= 200 KJ
Thus, the potential energy of the reactants is 200 KJ. Therefore, the correct answer is option +200 KJ
