(4) Equilibrium Flashcards
when does equilibrium occur
when amount of moles of reactants and products remains constant
when does dynamic equilibrium occur
when amount of moles of reactants and products remains constant bc the rate of forward reaction is equal to the rate of reverse reaction
what is homogeneous
when all reactants and products are the same physical state
what is the equilibrium constant equation
Kc = [products]ᵖ / [reactants]ʳ
units of conc
moldm⁻³
direction if conc of REACTANT inc or dec
inc- right, dec- left
direction if conc of PRODUCT inc or dec
inc- left, dec- right
direction if pressure inc or dec
inc- side with fewer moles, dec- side with more moles
direction if temp inc or dec in an EXOTHERMIC reaction
inc- left, dec- right
direction if temp inc or dec in an ENDOTHERMIC reaction
inc- right, dec- left
direction and reason for large Kc
right , [products]>[reactants]
direction and reason for small Kc
left, [reactants]>[products]
what is Kc affected by
ONLY change in temp
when will Kc have no units
when there is equal no. of moles of reactants and products
what happens if there is no units or volume value
it will cancel out equilibrium and you can just use mole values
