The surface coverage of N atoms obtained is θ = 0.015

Rationale

We can use the answer to the previous question to save some work here since the flux of incident molecules will be the same - the differences are that

  1. each nitrogen molecule that sticks gives rise to two adsorbed N atoms,
  2. the sticking probability is lower by a factor of 9

Hence,

Coverage , θ = 0.069 x (2/1) x (0.1/0.9)  ⇒  θ = 0.015
