location of more moles
shift to the left
no shift
4. When a system at equilibrium is subject to change the system tries to minimize the change by?
dissappearing
going to the direction where it will relieve the stress
expand

What happens to the equilibrium if we add hydrogen (H2)?
It shifts left, towards the reactants
It shifts right, towards the products
It does not shift
N2 (g) + 3 H2 (g) <=> 2 NH3 (g)
If the pressure in the system is increased, which substance(s) will increase in concentration?
CoCI42- +6H2O →Co(H2O)62+ + 4CI-
What will happen when CI- ions are added?
Position of equilibrium will shift to left and become more pink
Color of system will turn to all pink
Concentration of reactants and products remain unchanged
Position of equilibrium will shift to left to reduce the added CI- ions
2CrO42- + 2H+ → Cr2O72- + H2O
What will happen when H+ ions are added to the system?
Position of equilibrium will shift to left and become more yellow
Color of system will turn all yellow
Color of system will turn all orange
Equilibrium will shift to right and become more orange
