Consider the oxidation of nitric oxide to form NO_2 2NO_((g))+O_(2(g))rarr2NO_(2_((g)) (a) Express the rate of the reaction in terms of changes in the concentration of NO , O_2 and NO_2. (b) At a particular instant , when [O_2] is decreasing at 0.2 "mol L"^(-1)s^(-1) at what rate is [NO_2] increasing at that instant ? |

Answer» SOLUTION :(a) Rate `=-1/2(d[NO])/(dt)=(-d[O_2])/(dt)=1/2(d[NO_2])/(dt)` (b)`(-d[O_2])/(dt)=1/2(d[NO_2])/(dt)` `(d[NO_2])/(dt)=2XX(-d[O_2])/(dt)=2xx0.2" MOL L"^(-1)s^(-1) = 0.4 "mol L"^(-1)s^(-1)` |
