Nitric Oxide. NO reacts with oxygen to produce nitrogen dioxide.
2NO(g) + O2(g) → 2NO2(g)
The rate law for this reaction is
rate = k[NO]2 [O2]
Propose a mechanism for the above reaction.
Activated complex is the intermediate compound formed by reactants, which is highly unstable and readily changes into product. Those reactants which possess activation energy and collide in proper orientation can form activated complex which can easily form products.
Lower the activation energy, more easily activated complex will be formed and faster will be the reaction.
Activation energy = energy of activated complex - energy of reactants.
The rate of reaction
2NO + Cl2 → 2NOCl
is double when concentration of Cl2 is doubled and it becomes 8 times when concentrations of both NO and Cl2 are doubled. Deduce the order of this reaction.
