The decomposition of phosphine $(P H_{3})$ on tungsten at low pressure is a first-order reaction. It is because theNEET 2016 (Phase 2)

Answer:

Solution:

The rate is proportional to the surface coverage.

When pressure is so low that $αp < < 1$ ,

$Rate = \frac{k_{r} αp}{1 + αp} \approx k_{r} αp$ .
