Question

2 mole each of SO3, CO, SO2 and CO2 is taken in a one lit. vessel. If KC for SO3(g) + CO(g) SO2(g) + CO2(g) is 1/9 then

• A. Total no. of moles at equilibrium are less than 8
• B. n(SO3) + n(CO2) = 4
• C. [n(SO2)/n(CO)] < 1
• D. Both(2) and (3)

Answer 1

Answer: (D)

Both(2) and (3)

Answer 2

SO3(g) + CO(g) SO2 (g) + CO2 (g)

$9 = \left( \frac{2 + x}{2 - x} \right)^{2}$

2 2 2 2

2+x 2+x 2-x 2-x x = 1

neq = 3 + 3 + 1 + 1 = 8 n(SO3) + n(CO2) = 4

$\frac{n\left( SO_{2} \right)}{n(CO)} = \frac{1}{2} < 1$

Therefore, (4) option is correct
