Executive search firms:

a. choices charge job candidates a fee only after they accept a job.
b. help employers find the right people for jobs.
c. lease executive level employees to organizations on a long- and a short-term base.
d. advertise only in trade magazines.

B- help employers find the right people for jobs.

Explanation:

An executive search firm is paid firm which organisations adopt because they are  known for having experienced and professional recruiters who are experts in recruiting activities for organisations. Their role includes identifying the qualifications needed for a given role, creating a candidate pool to assess candidates’ ensuring their  skills, experience, and personalities align with the open position and directing the best candidate to the specific employer.

Most companies tend to adopt the Executive search firms especially when Role is new and  Beyond Internal Expertise or when such firm wants to remain confidential in its search.

Generally, recruiting the right people in the right roles is not easy also it is a process that requires investments of time, since  companies  have found out they are experts in helping employers find the right people for jobs, they have become a solution in that regard.

Explanation:

Particles A and C are shown as if they are on the same vertical line, which means with the same kinetic energy. Both particle A and C are to the lett of particle B, which means that the formers have a lower kinetic energy than the latter.

Since the likelyhood of a particle to participate in the reaction increases with the kinetic energy, particle B is more likely to participate in the reaction than particles A and C. Hence, the first choice is incorrect.

The graph, although not perfectly symmetrical, does show a bell shape, hence there are many particles will low kinetic energy and many particles with high kinetic energy. You cannot assert that most of the particles of the two gases have high high speeds. Hence, second statement is incorrect, too.

At high values of kinetic energy (toward the right of the curve), the line labeled T₁ is higher than the line labeled T₂, meaning that at T₁ more particles have an elevated kinetic energy than the number of particles that have an elevated kinetic energy at T₂.

On the other hand, at low values of kinetic energy (toward the left of the curve) the line T₂ is higher than the line T₁, meaning that at T₂ more particles have a low kinetic energy than the number of particles that have low kinetic energy at T₁.

Hence, the last two paragraphs are telling that the average kinetic energy of gas particles at T₂ is is lower than the average kinetic energy of gas particles at T₁.

Since the average speed is proportional the the square root of the temperature, the same trend for the average kinetic energy is true for the average speed, and you conclude that the last statement is true: "The average speed of gas particles at T₂ is lower than the average speed of gas particles at T₁".

Since more particles at T₁ have high kinetic energy than the number of particles at T₂ that have a high kinetic energy, more particles of gas at T₁ are likely to participate in the reaction  than the gas at T₂, and the third statement is incorrect.
