Consider the given reaction in which NC−NC− is the nucleophile and CH3CNCH3CN is the solvent. The reactant molecule has a structure with solid and dashed wedge bonds. A solid wedge () is used to show the bond that is above the plane of the paper, and a dashed wedge () is used to show the bond that is behind the plane of the paper.
Draw the product of the following reaction:
Consider this reaction:

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.

The lower the rate of a reaction the longer it takes to reach completion. The rate of a fast step has more effect on the overall reaction rate than the rate of a slow step. Catalysts decrease reaction rates. Reaction rates increase as concentrations of homogeneous catalysts increase. The fastest step in a reaction is called the rate-determining step. Solid catalysts do not affect reaction rates. As a reaction progresses its rate goes up.arrow_forward

The alternate pathway has a lower activation energy (AE), meaning that the reactant molecules do not need to collide with as much energy in order for a reaction to occur, so more collisions result in a reaction, so the reaction rate is faster.
