+ d. Consider the two reaction mechanisms: Mechanism (i): CyH6O3 + C2H4O2 --> C3H1005 Step A CH1005- ----> C,H,O4 + H2O Step B Mechanism (ii): C2H4O2 + H2SO4 --> C2H5O2* + HSOA Step 1 C2H5O+ + C,HO, ----> CHOs Step 2 CH11O5 ----> C,H,O4 + H2O + H* Step 3 H + HSO4 ------> H2SO4 Step 4 A catalyst increases reaction rate, is involved in the reaction mechanism, is regenerated at the end of the reaction, but is not involved in the overall reaction. Mechanism _ represents the reaction with the catalyst. The step that shows the catalyst is involved in the reaction is __ The step that shows the catalyst is regenerated is __.
