Consider the following system at equilibrium where AH-198 kJ, and K,= 34.5, at 1150 K:

2SO₂(g) + O2(g) 2SO3(g)

When 0.33 moles of SO3 (g) are added to the equilibrium system at constant temperature:

The value of Ke

O increases

O decreases

Oremains the same

The value of Qe

O is greater than Ke

O is equal to Ke

O is less than Ke

The reaction must

Orun in the forward direction to reestablish equilibrium

O run in the reverse direction to reestablish equilibrium

O remain in the current position, since it is already at equilibrium.

The concentration of SO₂ will

O increase

O decrease

Oremain the same
