A proposed mechanism for a reaction is:

C4H9Br>C4H9+ + Br-
C4H9+ + H2O> C4H9OH2
C4H9OH2+ + H2O ---> C4H9OH + H3O

a. Write the rate law expected for this mechanism.
b. What is the overall balanced equation for the reaction?
c. What are the intermediates in the proposed mechanism?
d. Write the chemical equation for the overall reaction

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
