Unit 7 Flashcards
If you decrease in pressure how do you find equilibrium
Follow the mouth of the > considering the coefficients of the equation
If you increase in pressure how do you find equilibrium
Follow the tail of the < of the coefficients in the reaction
If you increase the temperature how does coefficient in k change
Decrease in K
if k is less than one what does that mean for the reaction
it is reactant favored
if ksp is less than one what does that mean for the reaction
the solute doesn’t dissolves amazingly
how does K change when the reaction is reversed
The second K is an inverses
k2 = 1/K1
How does K change when coefficients are changed
K1=K1)^x(what multiplier)
how does K change when the equations need to be combined
the two equations are multiplied
if Q is less than K how does the reaction proceed
to the right
if Q is more than K how does the reaction proceed
to the left
how do you calculate partial pressure
counting up the total molecules in the diagram and then dividing the individually grouped molecules by how many there are and multiplying by the total pressure in the system to find each partial pressure
how do you find what happens to a system after equalimbrium is disrupted like doubling pressure
find the value of Q
the smaller the ka the ____ the pH
higher
what is the species at highest concentration for a weak acid or base
the reactnat or undissolved substance
what is the species at highest concentration for a strong acid or base
H3O or OH
what does a larger ka mean in terms of persent of ionixation
a larger ka means a higher percent of ionization
if theres a larger kb what does that mean for the pH
a larger pH becuase theres less H+ and more OH
strongest acids (7)
HCl
HClO3
HClO4
HSO4
HBr
HI
HNO3
Strongest Bases
LiOH
NaOH
KOH
RbOH
CsOH
Ca(OH)2
Sr(OH)2
Ba(OH)2
