Question

Write the equilibrium-constant expression for the reaction shown in terms of [SO2]
, [CO2], [CS2], and [O2]

.

2SO2(g)+CO2(g)↽−−⇀CS2(g)+3O2(g)

Answer 1

Solution:

2SO₂(g) + CO₂(g) ⇌ CS₂(g) + 3O₂(g)  

equilibrium constant for this reaction:

$K_{c} = \dfrac{[CS_{2}][O_{2}]^{3}}{[SO_{2}]^{2}[CO_{2}]}$
