How can you predict equilibrium shifts due ti changes in condition?
Le Chateliers principle
What does magnitude of Kc indicate?
1 indicates equilibrium halfway between reactants and products
Less that 1, favours left hand side, products
Greater than 1, favour right hand side, reactants
How does temperature affect Kc?
Only affected by temp, increase in temp shifts in endothermic direction, decrease in temp shifts in exothermic direction
How does change in conc affect Kc?
System no longer in equilibrium, shifts to restore ratio to original Kc value
How does change in pressure affect Kc?
System bo longer in equilibrium, shifts to restore ratio to original value
Summarise equilibrium constant
Value show position of equilibrium, written from balanced equation, changes with temp
