NEET levelSingle correct optionDifficulty 1 of 3ce170

One mole of $PCl X_{5}$ dissociates to the extent of 30\% in a closed vessel. The total number of moles of gas at equilibrium is

A $1.00$
B $0.70$
C $1.60$
D $1.30$

Answer: D

PCl X_{5}

:

1 - α = 0.70

;

PCl X_{3}

:

0.30

;

Cl X_{2}

:

0.30

. Total

= 1 + α = 1.30

mol.
