5.0 mmol SO₂(g) and 5.0 mmol O₂(g) are sealed in a 1.0-L container. The mixture is heated for several hours and sulfur trioxide forms.

Chemical analysis of the reaction mixture shows that 2.0 mmol SO₃(g) forms. Th e experiment is repeated, except with twice as much (10.0 mmol) SO₂(g) and O₂(g).

(a) Estimate the amount of SO₃(g) formed in the second experiment.

(b) Calculate Kc from the results of the first experiment.

(c) Define y as the change in the oxygen concentration, and write the polynomial equation needed to solve for y in the second experiment.
