The mechanism of the reaction
`2NO(g)+H_(2)(g)rarrN_(2)(g)+2H_(2)O(g)`, is:
Step1: `2NO(g)+H_(2)(g)overset(("slow"))rarrN_(2)+H_(2)O_(2)`
Step2: `H_(2)O_(2)+H_(2)overset("fast")rarr2H_(2)O`

For the reaction mechanism of the reaction {:(2NO(g),+,2H_(2)(g)),(to N_(2)(g),+,2H_(2)O(g)):} {:("Step I",2NO,overset(k_(1))hArr,N_(2)O_(2),,,K_(eq)"(fast)"),("Step II",N_(2)O_(2)+H_(2),overset(k_(2))rarr,N_(2)O+H_(2)O,,"(slow)"),("Step III",N_(2)O+H_(2),overset(k_(3))rarrr,N_(2)+H_(2)O,,"(fast)"):} Expression of rate of reaction is (Take K_(eq) xx k_(2) = k')

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.
