Question #9 only

Study the following reaction energy diagram: energy reactants Then answer the following questions about the chemical reaction. Does this reaction release or absorb energy? How many transition states occur during this reaction? Could this be an elementary reaction? If you said this reaction could not be elementary, then how many steps are in its mechanism? If you said this reaction could not be elementary, then enter the number of the step in its mechanism which is rate- determining. For example, if the first step is the rate- determining step, enter "1" here. П products release absorb neither yes no

The question is based on your experimentally determined rate law, how would doubling the concentration of crystal violet affect the reaction rate? The reaction rate was second order and crystal violet we used was 1.5×10^–5 M crystal violet solution.
