_________________ chemical reaction in which all chemical equilibria (all products and reactants) are in the same phase
homogenous equilibria
_______________ chemical reaction in which the chemical equilibria (all products and reactants) are in different phases
heterogenous equilibria
What is not included in equilibrium constant?
Solids and solvents
If Q
the forward reaction is favored
[R]>[P]
If Q>K then
the reverse reaction is favored
[R]
Does K change with concentration
no
Adding more reactants will
form more product
removing product will
form more product
Does changing pressure change K?
no
If volume decrease resulting in more moles on left side of equation then
the reaction will move right
If volume decrease resulting in more moles on right side of equation then
the reaction will move left
Inert gasses effect on K?
None
What is the one physical element that affects K?
Temperature
DELTA H= negative (-)
exothermic
DELTA H=positive (+)
endothermic
Exothermic reactions: heating will favor
reactant formation
Endothermic reactions: heating will favor
product formation
Endothermic: K will __________________ with temperature increase
increase
Exothermic: K will __________________ with temperature increase
decrease
___________________ The reaction between acid and base that results in salt and water
neutralization
__________________ proton donor and acceptor
amphiprotic
___________________ proton transfer between two identical molecules
autoprotolysis
Strong acid= weak conjugate base
weak acid= strong conjugate base
depronation=
acid
