Nitric oxide (NO) reacts with oxygen to ...

Nitric oxide `(NO)` reacts with oxygen to produce nitrogen dioxide :
`2NO(g)+O_(2)(g)to2NO_(2)(g)`
What is the predicated rate law if the mechanism is
`{:(NO(g)+O_(2)(g)hArrNO_(3)(g),,("fast")),(NO_(3)(g)+NO(g)to2NO_(2)(g),,("slow")):}`

Text Solution

Verified by Experts

From the slow step,
Rate `=k_(1)[NO_(3)][NO]`…………`(i)`
From fast step
Equlibrium constant `(K)=([NO_(3)])/([NO][O_(2)])`…………`(ii)`
Substituting the value of `[NO_(3)]` from equation `(ii)` into equation `(i)`, we get
Rate `=k.[NO]^(2)[O_(2)]`

Determining the rate law from a mechanism with an initial slow step: Ozone reacts with nitrogen dioxide to produce oxygen and dinitrogen pentoxide O_(3)(g)+2NO_(2)(g)rarrO_(2)(g)+N_(2)O_(5)(g) The proposed mechanism is O_(3)(g)+NO_(2)(g)overset(slow)rarr NO_(3)(g)+O_(2)(g) NO_(3)(g)+NO_(2)(g)overset("fast")rarrN_(2)O_(5)(g) What is the rate law predicted by this mechanism ? Strategy : The designations "slow" and "fast" indicate the relative rates of the steps. The rate is determined completely by the slow step, or rate-determining sterp.
