15 Flashcards
what does K value mean
greater than 1 product dominant less than is reactant
what does reversible mean
reaction can move forward and backward
what is the giveaway that reaction has reached dynamic equilibrium
it stops reacting
equilibrium constant
K
what is equilibrium constant relation to reaction speed
none
what happens to K when reaction is reversed
inverse K
what do you do to k is equation is multiplied by constant
put the K to a power
what happens to K if equations are added to eachother
multiply K values
how to find equilibrium constant in terms of partial pressure
just use partial pressure in equilibrium equation
what do you do to woods and pure liquids in equilibrium equation
neglect them
what is K unit
nothing
ICE table
Initial change Equilibrium
steps to use ice table
balance eq
calc change in concentration
use touch to balance change
sum the concentrations
used balanced eq and conversation to find K
reaction quotient
K at a point before equilibrium is reached
what does value of q in relation to k mean
if q is larger it means rxn will go to left
if q is smaller it means rxn will go to right
if q is same as K it mean its at equilibrijm
me chateliers principal
when equilibrium is shifted the equation will try to balance it
what happens to reaction when heat is added to exothermic product side
shifts to reactants
what happens when heat is added to reactant side endothermic
dhifts to product
why does adding heat make exo and endo reactions shift
heat is either product or reactant in them so increasing it counts as increasing the products or reactants
what is intert gas
has no affect on equilibrium
what happens when you change volume of equilibrium
you raise the equilibrium constant to the power that vol changed by
what happens to them equation if volume is decreased
side with less moles is favored
