Passage / Comprehension

An amount of 0.60 moles of CO taken in a 2.46 L vessel is maintained at 900 K along with a catalyst so that the following reaction can take place CO(g) + 2H₂ (g) ⇌ CH₃OH(g). Hydrogen is introduced until the total pressure of the system is 24 atm at equilibrium and 0.2 mole of methanol is formed.

Total moles of $H_{2}$ gas added till equilibrium established are $____$ .

Answer:

0.60

Solution:

$CO (g) + 2 H_{2} (g) ⇌ CH_{3} OH (g)$

Initial 0.6 a mole

$Eqm 0.4 a - 0.4$ $0.2$

$PV = nRT$

$24 \times 2.463 = (a + 0.2) \times 0.0821 \times 900$

$a = 0.6$
