Explain the effect of the solvent on the reaction kinetics with respect to an SN1 mechanism.
How to explain 50%/50% acetone/water & 60%/40% acetone/water with reference to the above to the above (from results half life was way less in 50/50)
According to the data chart, the Rate constant for the
hydrolysis of tertbutylchloride in 50/50 acetone/water (volume) is:
k=1.03E-2/min^1
The rate constant for the hydrolysis of tertbutylchloride in 60/40
acetone/water is: K=2.9E-3/min^-1

Open with Google Docs The reaction to the right describes the isomerization of dihydroxyacetone phosphate (DHAP) to glyceraldehyde-3-phosphate (GAP). It is a chemical equilibrium reaction that happens in the biochemical pathway that is part of the metabolism of glucose. The chemical equilibrium can be treated much like the dynamic equilibrium observed for the vapor pressure. Answer the following questions about this reaction: OH DHAP GAP GAP and the kinetics of GAP DHAP are first order processes. What are the rate...
