Intro to Equilibrium

Question 1

dynamic equilibrium

Answer 1

a balance between forward and reverse processes that are occurring simultaneously at equal rates

Question 2

why is a sealed soda bottle a dynamic equilibrium

Answer 2

the two phases of carbon dioxide are in dynamic equilibrium inside the sealed bottle since gaseous carbon dioxide is dissolving into liquid form at the same rate that the liquid form of carbon dioxide is being converted back to its gaseous form

Question 3

what is an irreversible reaction and give an example

Answer 3

reactions that occur in one direction. Ex. combustion of methane

Question 4

rate of forward process is equal to what?

Answer 4

is equal to the rate of reverse process

Question 5

distinguish between macroscopic and microscopic properties and explain

Answer 5

macroscopic (visible) properties are constant because the concentration of the reactants and products stops changing
microscopic (molecular) events continue to occur. The system is dynamic.

Question 6

Equilibrium can only be reached by starting with the reactants. True or False

Answer 6

False. Equilibrium can be reached by starting with reactants or products
