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.

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

particle a and c are more likely to participate in the reaction than particle b.
most of the particles of the two gases have very high speeds.
a fewer number of particles of gas at t1 are likely to participate in the reaction than the gas at t2.
the average speed of gas particles at t2 is lower than the average speed of gas particles at t1.
