When Forward reaction rate > reverse reaction rate...
The ___ are being made faster than the ___ and therefore there is a net gain in the amount of ___.

Concentration of reactants ____ and concentration of products ___

Answer explanation

When Forward reaction rate > reverse reaction rate...
The products are being made faster than the reactants and therefore there is a net gain in the amount of products.

Concentration of reactants decrease and concentration of products increase.

When Reverse reaction rate > forward reaction rate...
The ___ are being made faster than the ___ and therefore there is a net increase in the amount of ___.

Concentration of reactants ____ and concentration of products ___

Answer explanation

When Reverse reaction rate > forward reaction rate...
The reactants are being made faster than the products and therefore there is a net gain in the amount of reactants.

Concentration of reactants increase and concentration of products decrease.

Answer explanation

Whenever there's a gain in the reactants or products, its more likely to be favorable the side of the gain.

Same goes for a loss/removal but backwards. The side opposite of the loss/removal is more favorable.

k > 1 :: ___ are favored

k < 1 :: ___ are favored

k ≈ 1 :: both are favored ___.

___ of K tells us what is favored at equilibrium.

if k is super big: forward reaction ___ to ___.

if k is super small: forward reaction ___ takes ___.

Answer explanation

k > 1 :: products are favored

k < 1 :: reactants are favored

k ≈ 1 : both are favored equally

Magnitude of K tells us what is favored at equilibrium.

if k is super big : forward reaction goes to completion.

if k is super small: forward reaction barely takes place.

products, reactants, equally, magnitude, goes, completion, barely, place

For 2, pretend k is multiplied by x.
