Try Again Your answer is incorrect. • Row 1: Your answer for change in composition column is incorrect. • Row 2: Your answer for change in composition column is incorrect. Sulfur dioxide and oxygen react to form sulfur trioxide, like this: 2 SO₂(g) + O₂(g) → 2 SO 3(g) The reaction is exothermic. Suppose a mixture of SO₂, O₂ and SO3 has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. perturbation The temperature is lowered. change in composition The pressure of SO₂ will The temperature is raised. The pressure of SO3 will go up. go up. ↑ shift in equilibrium to the right to the left (none) to the right to the left (none)
