Chemistry - Chemical equilibrium & Le Chatelier's Principle

Question 1

When the rates of the forward and reverse reactions are equal leading to constant concentrations of reactants and products

Answer 1

Chemical equilibrium

Question 2

Reactions where products can turn back into reactants

Answer 2

Reversible reactions

Question 3

Expresses the ratio of the concentrations of products to reactants at equilibrium for a given reaction at a specific temperature

Answer 3

Equilibrium constant

Question 4

K > 1

Answer 4

The products are favored

Question 5

K < 1

Answer 5

The reactants are favored

Question 6

K = 1

Answer 6

the system is balanced

Question 7

states that if a system at equilibrium is disturbed by changes in concentration, temp, or pressure, the system will adjust to counteract the disturbance and reach a new equilibrium

Answer 7

Le Chatelier’s Principle

Question 8

An increase in temp in an exothermic reaction

Answer 8

shift to the left

Question 9

An increase in temp in an endothermic reaction

Answer 9

shift to the right

Question 10

An increase in pressure in an equation with gases

Answer 10

Shift towards the side with fewer gas molecules

Question 11

An increase in volume in an equation with gases

Answer 11

shifts towards the side with more gas molecules
