Explain the relationship between forward and reverse reactions at equilibrium and predict how

changing the amount of a reactant or product (creating a stress) will affect that relationship.

for example (select one from each section)

if the amount of (reactant or product) increases, the rate of the (forward or reverse) reaction will

(increase or decrease) to reach a new equilibrium.

if the amount of (reactant or product) decreases, the rate of the (forward or reverse) reaction will

(increase or decrease) to reach a new equilibrium.
