Some Basic Concepts Of Chemistry Question 199

Question: $100 m L$ of $P H_{3}$ on decomposition produced phosphorus and hydrogen. The change in volume is [MNR 1986]

Options:

A) $50 m L$ increase

B) $500 m L$ decrease

C) $900 m L$ decrease

D) Nil.

Show Answer

Answer:

Correct Answer: A

Solution:

$\underset{100 m l}{\underset{2 m l}{2 P H_{3}},}, \to \underset{(solid)}{2 P}, + \underset{150 m l}{\underset{3 m l}{3 H_{2}},},$ Increase in volume $= 150 m l - 100 m l = 50 m l$ increase.
