Question

at high temperature, so₂ and no₂ react according to the equation below. determine the equilibrium constant for this reaction by constructing an ice table, writing the equilibrium constant expression, and solving it. complete parts 1 - 2 before submitting your answer.
so₂(g) + no₂(g) ⇌ so₃(g) + no(g)

1. based on the set - up of your ice table, construct the expression for kc. each reaction participant must be represented by one tile. do not combine terms.
2. once the expression is constructed, solve for kc.

Explanation:

Step1: Write the balanced chemical equation

\[SO_2(g)+NO_2(g)
ightleftharpoons SO_3(g)+NO(g)\]

Step2: Recall the formula for the equilibrium - constant expression \(K_c\)

The equilibrium - constant expression \(K_c\) for a general reaction \(aA + bB
ightleftharpoons cC + dD\) is \(K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}\), where \([X]\) represents the molar concentration of species \(X\) at equilibrium.
For the reaction \(SO_2(g)+NO_2(g)
ightleftharpoons SO_3(g)+NO(g)\), \(a = 1\), \(b = 1\), \(c = 1\), \(d = 1\).

Step3: Construct the \(K_c\) expression

\[K_c=\frac{[SO_3][NO]}{[SO_2][NO_2]}\]

Answer:

\[K_c=\frac{[SO_3][NO]}{[SO_2][NO_2]}\]
