For the reaction mechanism:
H2 + 2NO → N2 + H2O2 (slow)
H2O2 + H2 2H2O (fast)
the rate law is rate
- k[H2] [NO]2
- k[H2O2]2
- k[N2][H2O2]2
- k[H2O2] [H2]

For a chemical reaction, R → P, it is found that the rate of a reaction doubles, when the concentration of R is increased two times. The order of the reaction is
The rate of a chemical reaction
- Increases as the reaction proceeds
- Decreases as the reaction proceeds
- May increase or decrease during the reaction
- Remains constant as the reaction proceeds
The rate constant of a reaction depends on
- Temperature
- Mass
- Weight
- Time
A zero order reaction is one
- Whose rate is affected by concentration.
- In which concentration of the reactants does not change with time.
- In which reactants do not react.
- In which one of the reactants is in large excess.
