(Old test) Using the bond dissociation energies on page 172, calculate t~e L\H for the overall reaction (reaction of 2-bromo~~-2-methylpropane with water that forms 2- methyl-2-propanol) Show calculations. . The above overall reaction is considered to be a) endergonic b) exergonic 4. 5. Calculate Llli for the following reactions a) C"-'?L~'2.C(~-t ttl -7 C\'\;L~z..O~ -tctt~t b) T ttcl 6. (Old test) The first step of the reaction mechanism is much slower than the second step, which in turn is slower than the third step. Based on all the information given and your calculations for AH, draw a qualitative reaction energy diagram for the reaction of 2- bromo-2-methylpropane with water.
