Question

question 4 (1 point)
potential energy diagram
use the potential energy diagram. what is shown by the letter b?
the activation energy of the forward reaction
the activation energy of the reverse reaction
the transition state
the heat of reaction
the entropy of the reaction

Explanation:

In a potential - energy diagram, the activation energy of the forward reaction is the energy difference between the reactants and the transition state. The heat of reaction is the energy difference between the reactants and the products (shown by \(C\)). The transition state is the highest - energy point on the diagram. The entropy of the reaction is not directly represented as a vertical segment in a simple potential - energy diagram.

For the forward reaction, the activation energy is the energy that reactants need to overcome to form products. In the given diagram, the segment \(B\) represents the energy barrier that reactants must cross. This energy barrier is the activation energy of the forward reaction.

Answer:

the activation energy of the forward reaction
