CHEM TEST 3

When a substance is removed the reaction will…

will shift to the side the substance was removed to replace it

When a substance is added the reaction will…

shift away from the side of the added substance in order to redistribute the concentration

If volume is decreased (pressure increases) the reaction will…

shift to the side with fewer moles

If volume is increased (pressure decreases) the reaction will…

shift to the side with more moles

If the moles of gas are equal on both the product and reactant sides, then…

changing volume/pressure has no effect on equilibrium

When an inert gas is added at constant volume..

equilibrium does not shift

When inert gas is added at constant pressure the reaction will..

shift to the side with more moles of gas

When heat is added to an exothermic reaction

K will decrease as temp increases

What is the only thing that changes K?

Temperature

When a cataylst is added..

equilibrium will not shift
