Transcribed Image Text:A reaction profile (not to scale!) for the reaction C₂H5OH + Br¯ → C₂H5Br + OH¯ is shown below: Increasing energy C₂H₂OH+ Br 161 kJ C₂H₂Br + OH- 71 kJ Reaction progress

According to the collision theory of reaction rates, which of the following is/are true?
(Select all that apply.)
In the presence of a catalyst, the value of activation energy for the reaction would be smaller than 161 kJ.
Raising the temperature would increase the rate of the reaction by increasing the number of successful C₂H5OH + Br collisions.
Increasing the concentrations of C2H5OH + Br¯ would increase the rate of the reaction.
In the presence of a catalyst, the value of energy difference between products and reactant will be larger than 71 kJ.
Raising the temperature would increase the rate of the reaction because the value of activation energy would be smaller than 161 kJ at a higher
temperature.

Expert Solution

Step 1

The collision theory of reaction rates states that the rate of a chemical reaction is proportional to the frequency of collisions between the reactant molecules, as well as the fraction of these collisions that have sufficient energy (equal to or greater than the activation energy) and proper orientation to lead to a chemical reaction. Based on this theory, we can evaluate the given statements as follows:
