Dynamic Equilibrium - SC12 Flashcards
What is dynamic equilibrium?
When a reaction hits a certain point whereby forward and backwards reactions still occur but the percentages of reactants / products are no longer changing
What are the 4 factors affecting equilibrium?
temp increase, pressure increase, concentration of a reacting substance increase, catalyst added
under what conditions may a reversible reaction reach equilibrium?
in a closed system where no substances enter or leave
What of the dynamic equilibrium is affected by changes in condition?
position of dynamic equilibrium and how quickly equilibrium is reached
how does temp increase affect the position of equilibrium?
the eq moves in the direction of the endothermic reaction
how does pressure increase in reactions involving gases affect the position of equilibrium?
the eq moves towards the side of the balanced equation with fewer molecules of reacting gas
how does concentration of reacting substance increase affect the position of equilibrium?
eq moves away from reacting substance in balanced equation
how does catalyst added affect the position of equilibrium?
no change
