Can someone please provide an explanation for why each one is
faster than the other for SN1 reactions.

Can someone please provide an explanation for why each one is faster than the other for...
This is a multiple question discussion. Can someone please help and provide insight with definitions and examples? Compare and contrast SN1, SN2, E1 and E2 reactions. What are some obvious similarities and differences between each reaction pathway? What are the requirements for each reaction to work? Discuss why SN2 is in direct competition with E2 while SN1 is in direct competition with the E1 reaction pathway. What is the rate expression for each? Which reactions are concerted? Which reactions are...
