1. The mechanism for hydrogen peroxide decomposition is thought to occur in two step:
step 1: H2O2+ I ------> IO + H2O
step 2: IO + H2O2 --------> I + H2O + O2
a. describe each step in the mechanism as unimolecular ,bimolecular or termolecular ?
b. which species in the mechanism acts as an intermediate.?
c. which species in the mechanism acts as catalyst.?
d. what is the net reaction?
Homework Answers
a) no of molecules involved in both steps are 2 so bimolecula
b) formed and consumed during the reaction - intermediate = IO
c) used and remained in the reaction - catalyst = I
d) net reaction obtained by adding two
steps
