what is the correct equilibrium constant expression for the following reaction?
2ncl₃(g) ⇌ n₂(g) + 3cl₂(g)
options:
kₑₚ = n₂cl₂³ / ncl₃²
kₑₚ = ncl₃² / n₂cl₂³
kₑₚ = n₂cl₂ / ncl₃
kₑₚ = ncl₃ / n₂cl₂
kₑₚ = n₂³cl₂³ / ncl₃³

use the following information to answer the next question.
carbon monoxide (co(g)) is a colourless and odourless
gas. it is extremely toxic but has wide applications in
chemical manufacturing. it is produced in the following

Explanation:

Step1: Recall the formula for equilibrium constant

For a general reaction \(aA + bB
ightleftharpoons cC + dD\), the equilibrium constant \(K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}\), where \([A]\), \([B]\), \([C]\), \([D]\) are the molar concentrations of species \(A\), \(B\), \(C\), \(D\) respectively and \(a\), \(b\), \(c\), \(d\) are the stoichiometric coefficients.

Step2: Apply the formula to the given reaction

For the reaction \(2NCl_{3}(g)
ightleftharpoons N_{2}(g)+3Cl_{2}(g)\), here \(a = 2\) (for \(NCl_{3}\)), \(c = 1\) (for \(N_{2}\)) and \(d=3\) (for \(Cl_{2}\)).
So, \(K_{eq}=\frac{[N_{2}][Cl_{2}]^{3}}{[NCl_{3}]^{2}}\)

Answer:

The first option \(K_{eq}=\frac{[N_{2}][Cl_{2}]^{3}}{[NCl_{3}]^{2}}\) is correct.
