Question

examine the figure below for the following question:which letter represents the activation energy of the forward reaction?a b c d none of the above

Explanation:

Activation energy is the minimum energy required to start a chemical reaction. In a potential - energy diagram for a reaction, it is the energy difference between the reactants and the transition state (the peak of the energy curve).

• In the given diagram, letter \(A\) represents the activation energy of the forward reaction as it is the energy difference between the reactants (lower energy level) and the transition state (the highest point \(D\)).
• Letter \(B\) is the activation energy of the reverse reaction (energy difference between products and transition state).
• Letter \(C\) is the energy difference between products and reactants (enthalpy change of the reaction).

Answer:

A.
