Question

Nitrogen dioxide `(NO_(2))` reacts with fluroine `(F_(2))` to form nitryl fluroide `(NO_(2)F)` according to the reaction.
`2NO_(2)(g) + F_(2) to 2NO_(2)F(g)`
Write the instaneous rate of reaction in terms of
i) rate of formation of `NO_(2)F`,
ii) Rate of disappearance of `NO_(2)`,
iii) rate of disappearance of `F_(2)`

Answer 1

i) Rate of formation of `NO_(2)F1(r ) = (d(NO_(2)F))/(dt)`
ii) Rate of disappearance of `NO_(2)`(r) = `(-d(NO_(2)))/(dt)`
iii) Rate of disappearance of `F_(2)`(r) = `(-d(F_(2)))/(dt)`
