equilibria 1.6 Flashcards
what does equilibrium mean
when rate of forwards reaction is the same as backwards reaction
what can equilibrium only happen in
closed systems
what does la chateliers principle say
in equilibrium if conditions are changed the equilibrium will move to counteract this
if you increase the concentration of products/reactants what happens
equilibrium will move to the left/right
what does increasing pressure do to equilibrium
shifts it to the side with fewer gas molecules
increasing temp means equilibrium will move where
to the endothermic side positive ΔH
decreasing temp moves equilibrium where
exothermic side with negative ΔH
what effects do catalysts have to equilibrium
NO EFFECT but they can increase yeild
what conditions are needed for making ethanol
60 atmospheres
300 degrees
phosphoric acid catalyst
what is the forwards reaction in making ethanol
exothermic
what will lowering temp do to ethanol reaction
lower ROR as 300 degrees is in between yield and rate
what does increasing pressure do for the reaction
increases ethanol production but is expensive
how do u calculate Kc
[C][D]/[A][B]
whats the acronym for working out Kc in harder equations
ICE
