Equilibria Flashcards
1
Q
reversible reaction
A
forward and backward at equal rates
products and reactant concentrations remain constant
2
Q
dynamic equilibrium
A
in a closed system
nothing can go in or out
3
Q
le chatelier’s principle
A
if external conditions change the equilibrium will shift to oppose the change
4
Q
temp
A
favours Endo
absorbs heat
5
Q
pressure
A
increase favours side with fewer moles as this will release build up of pressure
6
Q
Kc
A
indicates position of equilibrium for a reaction at a certain temp
[C]^c [D]^d / [A]^a [B]^b
7
Q
moles of reactant at equliburum
A
initial moles = moles reacted
8
Q
Kc is affected by
A
temp, not conc or catalyst
only works in homogenous reactions - all reactants and products in the same state
