Question

1) Consider the following reaction where K_c = 10.5 at 350 K:

2 CH₂Cl₂(g) -------> CH₄(g) + CCl₄(g)

A reaction mixture was found to contain 1.11×10^-2moles of CH₂Cl₂(g), 2.35×10^-2moles of CH₄(g), and 4.10×10^-2moles of CCl₄(g), in a 1.00 liter container.

Indicate True (T) or False (F) for each of the following:

___TF 1. In order to reach equilibrium CH₂Cl₂(g) must be produced .
___TF 2. In order to reach equilibrium K_c must decrease .
___TF 3. In order to reach equilibrium CH₄must be produced .
___TF 4. Q_c is less than K_c.
___TF 5. The reaction is at equilibrium. No further reaction will occur.

2) Consider the following reaction where K_c = 34.5 at 1150K:

2SO₂(g) + O₂(g) ------> 2SO₃(g)

A reaction mixture was found to contain 4.14×10^-2 moles of SO₂(g), 4.31×10^-2 moles of O₂(g) and 3.84×10^-2 moles of SO₃(g), in a 1.00 Liter container.

Indicate True (T) or False (F) for each of the following:

___TF 1. In order to reach equilibrium SO₃(g) must be consumed.
___TF 2. In order to reach equilibrium K_c must increase.
___TF 3. In order to reach equilibrium SO₂ must be produced.
___TF 4. Q_c is less than K_c.
___TF 5. The reaction is at equilibrium. No further reaction will occur.
