Composite Reactions & the Steady State Approximation

COMPOSITE REACTIONS AND THE STEADY STATE APPROXIMATION

Hint

For the general case, aA + bB → Product, the rate of the reaction is:

Rate = k[A]α[B]β

Note : a = α and b = β only if the reaction is elementary.

Review Question

The rate law for the reaction

2NO2 + F2 → 2NO2F
has been experimentally determined as
r = k[NO2][F2]
Therefore
The reaction is elementary

The reaction is not elementary
