Equilibria Flashcards
define the term dynamic equilibrium?
the rate of the forward reaction is equal to the rate of the reverse reaction
what is an essential condition for equilibrium to me reached?
A closed system
state Le Chatlier’s principle
if the conditions of dynamic equilibrium in a closed system are changed, the equilibrium shifts to oppose that change
what effect does a catalyst have on the position of equilibrium?
No effect
what condition affects the value of Kc?
Temperature
what type of system is Kc relevant for?
Homogenous systems in equilibrium
what does Kc being greater or lesser than 1 suggest about the position of equilibrium?
Greater than 1 = position at right (favours reactants)
Less than 1 = position at left (favours products)
what effect does decreasing the temperature in an endothermic reaction have on Kc?
Kc decreases
what effect does increasing the temperature in an enothermic reaction have on Kc?
Kc increases
what effect does decreasing the temperature in an exothermic reaction have on Kc?
Kc increases
what effect does increasing the temperature in an exothermic reaction have on Kc?
Kc decreases
