Answer:
K = 3.45
Explanation:
In the reaction:
SO₂(g) + NO₂(g) ⇄ SO₃(g) + NO(g)
And K is:
K = [SO₃] [NO] / [SO₂] [NO₂]
<em>Where [] are concentrations in equilibrium, as volume is 1L, [] could be taken as moles.</em>
Equilibrium concentrations are:
[SO₂] = 2.00 moles - X
[NO₂] = 2.00 moles - X
[SO₃] = X
[NO] = X
AS moles of NO are 1.3 moles, X = 1.3 moles
Replacing:
[SO₂] = 0.7 moles = 0.7M
[NO₂] = 0.7M
[SO₃] = 1.3M
[NO] = 1.3M
K = 1.3M² / 0.7M²
<h3>K = 3.45</h3>
