When the volume of a reaction vessel for a gas system at equilibrium is increased

Question

When the volume of a reaction vessel for a gas system at equilibrium is increased

a)The equilibrium is not changed

b)The equilibrium shifts to the RHS

c)The equilibrium shifts to the LHS

d)Not enough information is given

Answer 1

When the volume of a gaseous reaction is INCREASED, the pressure will decrease, and so the equilibrium will shift to the side of the equation that has the greater number of moles of gas. It could be the RHS, the LHS, or not at all if the moles of gas are equal on both sides. Since you didn't provide the reaction, we can't tell. So, not enough information is given.
