1.

Adding more reactant to a system at equilibrium

shifts it toward reactants
changes K
has no effect
shifts the equilibrium toward products
2.

Removing a product

shifts toward reactants
shifts the equilibrium toward products
changes K
stops the reaction
3.

Decreasing the volume of a gaseous equilibrium shifts it toward

the side with more moles of gas
the side with fewer moles of gas
reactants always
products always
4.

For an endothermic reaction, increasing the temperature

increases K and shifts toward products
decreases K
has no effect on K
shifts toward reactants
5.

Adding a catalyst to a system at equilibrium

does not change the equilibrium position
shifts toward products
shifts toward reactants
changes K
6.

Adding an inert gas at constant volume

shifts to the side with fewer moles
has no effect on the equilibrium position
shifts to more moles
changes K
7.

For N₂O₄(g) ⇌ 2NO₂(g), increasing the volume

shifts toward N₂O₄
has no effect
shifts toward NO₂
changes K
8.

For H₂(g) + I₂(g) ⇌ 2HI(g), changing the volume

does not shift the equilibrium
shifts right
shifts left
changes K
9.

After a stress is applied, the system shifts until

Q equals zero
K changes
Q equals K again
all reactants are used
10.

Diluting an aqueous equilibrium shifts it toward

the side with fewer dissolved particles
neither side
the solid
the side with more dissolved particles
