Study the following reaction energy diagram:0reactantsenergyproductsThen answer the following questions about the chemical reaction.Does this reaction release or absorb energy? releaseabsorbneitherHow many transition states occur duringthis reaction? Could this be an elementary reaction? yesnoIf 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.

Below are the elementary steps that make-up the reaction mechanism for the following reaction.F2 + 2 NO2 → 2 NO2FStep 1: F2 + 2 NO2 → NO2F + F + NO2 (slow)Step 2: F + NO2 → NO2F (very fast)Which is the rate determining step?Group of answer choicesStep 1Step 2

Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is exothermic.Note: Because the sketches are only qualitative, the energies in them don't have to be exact. They only have to have the right relationship to each other. For example, if one energy is less than another, that fact should be clear in your sketch.Uncatalyzed reactionCatalyzed reactionenergyenergyreactantsEaproductsreactantsEaproductsreaction coordinatereaction coordinate
