Question

Nitrogen dioxide reacts with fluorine to yield nitroyl fluoride as
NO2(g) + F2(g) -- 2 NO2F(g) Write average rate of reaction in terms
of (i) rate of formation of NO2F (ii) rate of disappearance of NO2

Avni · Accepted Answer

The reaction is:
2NO2(g) + F2(g) →2NO2F(g)

We can write that:
i) Rate of formation of NO2F = ∆[NO2F]∆tandRate of
reaction of F2 = -∆[F2]∆tDividing each rate by the
corresponding coefficients and equating them we get:
12∆[NO2F]∆t = -∆[F2]∆t

Or we can say that the rate of formation of NO2F is
twice the rate of disappearance of F2

ii) Rate of disappearance of NO2 = -∆[NO2]∆tDividing
each rate by the corresponding coefficients and equating them we
get: 12∆[NO2F]∆t = -12∆[NO2]∆t

Or we can say that the rate of disappearance of NO2 is
equal to the rate of formation of NO2F
