The graph shows the distribution of energy in the particles of 2 gas samples at different temperatures, t1 and t2. a, b, and c represent individual particles.
based on the graph, which of the following statements is likely to be true?
a. particle a is more likely to participate in the reaction than particle b.
b. particle c is more likely to participate in the reaction than particle b.
c. the number of particles able to undergo a chemical reaction is less than the number that is not able to.
d. more gas particles participate in the reaction at t2 than at t1.
