An unknown compound

\mathrm{A}

dissociates at

500^{\circ} \mathrm{C}

to give products as follows

A(g) \rightleftarrows B(g)+C(g)+D(g)

Vapour density of the equilibrium mixture is 50 when it dissociates to the extent to

10 \%

. What will be the molecular weight of compound A-

View answer and explanation

Correct option: A

120

Option A (120) is correct because the molecular weight of compound A is calculated using the vapour density at equilibrium and the degree of dissociation.
