The decomposition of phosphine (pH_(3))on tungsten at low pressure is – InterviewSolution

1.	The decomposition of phosphine (pH_(3))on tungsten at low pressure is a first-order reaction .It is because the ……..
Answer» rate is independent of the surface COVERAGE. rate of DECOMPOSITION is very slow. rate is PROPORTIONAL to the surface coverage rate is inversely proportional to the surface coverage Solution :The decompositional to the surface coverage pressure is a first order REACTION because rate is proportional to the surface coverage
