Question

Consider the following system at equilibrium where delta H° = 198 kJ, and K_c = 2.90×10^-2, at 1150 K.

2SO₃(g) <------>2SO₂(g) + O₂(g)

When 0.19 moles of SO₂(g) are removed from the equilibrium system at constant temperature:

The value of K_c _________

a.)increases

b.)decreases

c.)remains the same.

The value of Q_c _________

a.)is greater than

b.)is equal to

c.)is less than K_c.

The reaction must

a.)run in the forward direction to restablish equilibrium.
b.)run in the reverse direction to restablish equilibrium.
c.)remain the same. It is already at equilibrium.

The concentration of O₂ will _________

a.)increase

b.)decrease

c.)remain the same.
