Correct answer is (a) 0.14, 0.326

Q. The reaction, $PC l_{5} ⇌ PC l_{3} + C l_{2}$ is started in a $5$ litre container by taking one mole of $PC l_{5} .$ If $0.3$ mole of $PC l_{5}$ is there at equilibrium, concentration of $PC l_{3}$ and $K_{c}$ will respectively be:

$0.14, 0.326$

$0.12, 0.120$

$0.07, 0.150$

$20, 0.010$

Correct answer is (a) $0.14, 0.326$
