Based on the information given regarding the energy, the true statement is C. "The number of particles able to undergo a chemical reaction is less than the number that is not able to."
<h3>What is energy?</h3>It should be noted that energy is the quantitative property that must be transferred to a body to perform work on the body.
In this case, the graph is shown with two inverted graph curves running close to each other, and one of the curves labeled T1 is slightly more spread out than the other labeled T2.
Here, T1 is the only sample with a particle able to react. Particle B is more likely to participate in the reaction than particle A and the number of particles able to undergo a chemical reaction is less than the number that is not able to.

Answer:
The degree of dissociation of acetic acid is 0.08448.
The pH of the solution is 3.72.
Explanation:
The
The value of the dissociation constant =
Initial concentration of the acetic acid = [HAc] =c = 0.00225
Degree of dissociation = α
Initially
c
At equilibrium ;
(c-cα) cα cα
The expression of dissociation constant is given as:
Solving for α:
α = 0.08448
The degree of dissociation of acetic acid is 0.08448.
The pH of the solution ;
