Chapter 15 equilibrium Flashcards
the expression for the equilibrium constant
product of products raised to molar coefficients/ product of reactants raised to molar coefficients
are solids and liquids involved in the equation for the equilibrium constant
No the concentration does not work with pure substances
if Kc is less than 1
reactants are favored
if Kc is greater than 1
products are favored
Does the favoring of the reactants or products depend on the initial concentrations of the reactants and products given KA?
NO
how to calculate the M of a substance given the M of the other substances and Ka
solve for M with the expression for the equilibrium constant
Predict whether the reaction will shift left, shift right, or remain unchanged if products is added to the reaction mixture.
left
Predict whether the reaction will shift left, shift right, or remain unchanged if products is removed from the reaction mixture.
right
Predict whether the reaction will shift left, shift right, or remain unchanged if reactants are added to the reaction mixture.
right
Predict whether the reaction will shift left, shift right, or remain unchanged if reactants are removed to the reaction mixture.
left
if a reactant or product that is a solid or liquid is either added or removed what happens to equilibriunm
nothing
if the equilibrium constant is 1 are products and reactants equal
nope, it just means that they are relatively close
when 10^3
assume the reaction goes to completion
when 10^-3>Ka
assume the reaction doesnt really happen. in your ice table the x is not counted for the reactants. just for the projects
dynamic equilibrium
when the concentration of the products and the reactants stop changing
