(c)
A+B→AB (f ast)
AB+A→Products (slow)
(d)
A+A→A 2 (f ast)
A 2 +B→Products (slow)
- The following three-step mechanism is proposed for the reaction between NO and H 2 :
NO+NO→N 2 O 2 (f ast)
N 2 O 2 +H 2 →N 2 O+H 2 O (slow)
N 2 O+H 2 →N 2 +H 2 O (f ast)
(a) What is the rate determining step?
(b) Write the balanced equation for the overall reaction.
(c) Are there any intermediates? if so, state what they are.

Points to Consider
Do reactions only go in one direction? Can reverse reactions occur?
