PH₃(g) decomposes on heating to produce phosphorous and hydrogen. The change in volume when 100 ml of such gas decomposed is

Answer:

Solution:

$4 P H_{3} (g) He a t P_{4} (s) + 6 H_{2} (g)$

Volume of $H_{2}$ formed by the decomposition of $100 m l$ of $P H_{3}$ = $100 \times \frac{6}{4} = 150 m l$

Thus, the change in volume = $(150 - 100) = 50 m l$ .
