Equilibrium Concepts
These are the same when a reaction is at equilibrium
rate fwd and rev reactions
Unit we use to find Kc
M
A + B --> C
Adding more "B" will cause the reaction to do this
shift right
If Q > K, this means there is too much of this
product
The chemical formula of water is H2O; the compound H2O2, which can be used in hair bleaches, is typically referred to by what two-word name?
hydrogen peroxide
reversible
A + B --> C
Removing "B" will cause the reaction to do this
shift left
If a reaction is exothermic, where should we write "heat" in the equation?
product side (right)
If Q > K, how will a reaction shift?
left
What element, atomic number 3 on the periodic table, is an essential component of batteries often used to store harvested solar energy?
Lithium
We can describe equilibrium using an equilibrium constant, which is basically a ratio comparing these divided by reactants
products
A (g)+ B (g)--> C (g)
Increasing the pressure will cause the reaction to:
Shift right
How will an endothermic reaction shift if heated?
right
If Q < K, you have too little...

Winning for "their synthesis of new radioactive elements," the second woman to win the Nobel Prize for Chemistry was the daughter of two other Nobel Prize winners. What was the family's surname?
Curie
Kc is based on concentration while Kp is based on this
pressure of a gas
A (g)+ B (g)--> C (g)
Decreasing the volume will cause the reaction to:
shift left
How will an exothermic reaction shift when heated?
left
If Q = K, you are ...
at equilibrium
What synthetic chemical element, atomic number 104, is named after a famous New Zealand physicist?
Rutherfordium
If K >>>> 1, a reaction favors...
the forward direction
If K <<<< 1, a reaction favors...
the reverse direction
Pop up trivia: What do you think Ka is used for?
Equilibrium constant for an acid
Q is like K in setup, but it is measured...
when you are not at equilibrium
What is the name of chemist Dr. Bunsen Honeydew's redheaded assistant on "The Muppet Show?"
Beaker
