Which factor in the arrhenius equation represents the frequency of collisions and the probability that the collisions are favorably oriented: k = ae^(-e_a"/"rt)

the factor A

Explanation:

This variable in the equation is called "pre-exponential factor" or "frequency factor", it has the same units of the rate constant and depends on the reaction order. The value of A is experimentally determined for each reaction, as the question says, this value is associated with the probability of the molecules getting well oriented for forms the products (this requires energy), if they are not rightly oriented, then the products are not formed.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

c, liquids evaporate, creating a gas
