No effect on Equilibrium
Impact of a catalyst on equilibrium
Favoring products: what is the inequality?When favoring products it's a >50% reaction (The arrow will point to the side favored)
Favoring products: what is the inequality?
Concentration of products over reactants with coefficients representing the exponents
Whats the formula for Kc?
Temperature changes will shift an equilibrium to products or reactants but unlike concentration changes there will be a different Kc value.
What effect does temp have on equilibrium? On Kc?
Increasing the B values concentration causes that side to increase making a shift right.
Reactants are loosing and therefore products are gaining
A + 3B <-> 2C + D
Increasing the concentration of B would create a shift ______. What is happening to the reactants and products?
When writing a KC expression what must you not include?
Do not include liquids or solids in the KC or equilibrium concentration sections of an ICE table
What effect does pressure change have on equilibrium?
A change in pressure will cause the side of highest pressure to respond according to the movement
Properties of an acid
pH lower than 7, tastes sour, conductive, contains hydronium ions, turns blue litmus paper red.
Properties of a base
pH above 7, tastes bitter, contains hydroxide ions, turns red litmus blue
How do you determine which side is favored in an acid base equilibrium?
Place one finger on the acid, one on the base. If the acid is above then the reaction favors products, if the base is higher the reaction favors reactants
Arrhenius' theory and modified Arrhenius
Arrhenius: An acid is a substance containing Hydrogen ions
Modified Arrhenius: A base is a substance containing hydronium ions
Steps for Bronsted-Lowry
1. List all the species present (dissociate any ionic compounds)
2. Always add water
3. Determine which species are acids and which are bases and then specify the strongest acid and strongest base.
4. React SA and SB together and transfer H+ ion
5. Products will have the conjugate pairs as well as possess an either positive or negative charge.
Other term for KC
Equilibrium constant, equilibrium law expression
How can you tell if products or reactants are favored?
If KC is >1 products are favored
If KC = 1 then niether side is favored
If KC is < 1 reactants are favored
