1N2 + 3H2 →2NH3
When the pressure on the system is increased, the equilibrium position shifts to the right. Why?
To increase the amount of products
To reduce the pressure, as the right side has fewer molecules of gas
Keq will increase when it is shifted to the right
To increase the pressure, as the right side has more molecules of gas
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
Heat + 1 N2O4 → 2 NO2
What will happen when the temperature is increased?
Position of equilibrium will shift to left and become lighter in color
Position of equilibrium will shift to right and become more brown
No change in position of equilibrium
Position of equilibrium will shift to right and become lighter in color
CoCI42- +6H2O →Co(H2O)62+ + 4CI- + Heat
What will happen when the temperature is increased?
Position of equilibrium will shift to left and become more blue
Position of equilibrium will shift to right and become more pink
No change in position of equilibrium
Position of equilibrium will shift to left and become more pink
2CrO42- + 2H+→Cr2O72- + H2O
What will happen when OH- ions are added to the system? HINT: They remove the H+ ions.
Position of equilibrium will shift to right and become more orange
Position of equilibrium will shift to left and become more yellow
Position of equilibrium will shift to right and become more yellow
OH- ions will not react, and thus no change is seen.
