Question 1

What determines whether a reaction can occur?

Answer 1

Thermodynamics

Question 2

What does it mean for a chemical equilibrium to be dynamic

Answer 2

The particles involved are constantly moving and reacting

Question 3

What determines how fast a reaction will occur?

Answer 3

Kinetics

Question 4

When the forward reaction rate matches the reverse reaction rate

Answer 4

Chemical equilibrium

Question 5

What states “at a fixed temperature, a chemical system may reach a point at which the ratio of the concentration of the products of the reactance is constant”

Answer 5

The law of chemical equilibrium

Question 6

What states that when a reversible process is disturbed, it will proceed in the direction that relieves the stress

Answer 6

Le Châtelier’s principle

Question 7

Substances that change the rate of a reaction without undergoing any permanent change themselves

Answer 7

Catalysts

Question 8

A numerical expression of the ratio of the products to reactions at equilibrium. Each concentration in the expression is raised to the power that matches the substances coefficient in the balanced chemical equation

Answer 8

Equilibrium constant

Question 9

A reaction that proceeds in a forward and reverse direction so that products can change back into reactants and an equilibrium can be reached

Answer 9

Reversible reaction

Question 10

A chemical system at equilibrium in which all the reactants and products are in the same state of matter

Answer 10

Homogeneous equilibrium
