Question

The graph shows the distribution of energy in the particles of two gas samples at different temperatures, T1 and T2. A, B, and C represent individual particles.

A graph is shown with two inverted graph curves running close to each other. One of the curves labeled T1 is slightly more spread out than the other labeled T2. The x axis of the graph has the title Kinetic Energy. The y axis of the graph has the title Number of Particles. A vertical line perpendicular to the x axis is shown. This vertical line is labeled Activation Energy. A point labeled B is shown on the right hand side of the vertical line. A point labeled A is shown in the lower left side of the vertical line. A particle labeled C is shown in the upper left side of the vertical line.

Based on the graph, which of the following statements is likely to be true?

Particle A is more likely to participate in the reaction than particle B.
Particle C is more likely to participate in the reaction than particle B.
The number of particles able to undergo a chemical reaction is less than the number that is not able to.
More gas particles participate in the reaction at T2 than at T1.

Answer 1

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."

What is energy?

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.
