Hydrazine (N2H4) is a significant industrial chemical used in a variety of applications. It is commonly produced from ammonia (NH3) as well as the hypochlorite ion (OCI-) A proposed mechanism is
NH3 + OCI --> NH2CL + OH
NH2Cl + NH3 --> N2H5 + Cl
N2H5 + OH --> N2H4 + H2O
a State the overall reaction represented by this mechanism
b Define what are the reaction intermediates if any?
c State the rate law predicted by the mechanism above.
