A 25 L Flask Is Filled with 0

question 3

Multiple Choice

A 2.5 L flask is filled with 0.25 mol SO₃,0.20 mol SO₂,and 0.40 mol O₂,and allowed to reach equilibrium.Assume the temperature of the mixture is chosen so that K_c = 0.12.Predict the effect on the concentration of SO₃ as equilibrium is achieved by using Q,the reaction quotient.
2 SO₃(g) 2 SO₂(g) + O₂(g)

• A) [SO₃] will decrease because Q > K.
• B) [SO₃] will decrease because Q < K.
• C) [SO₃] will increase because Q < K.
• D) [SO₃] will increase because Q > K.
• E) [SO₃] will remain the same because Q = K.
