Challenge Problems
Push your limits with advanced challenges
If 1.0 mol of A and 3.0 mol of B are mixed in a closed container, and equilibrium is established with products C and D at a concentration of 0.5 M for C and 0.5 M for D, what is K? Also, if the concentration of A is later increased to 2.0 M, what will happen to the equilibrium?
💡 Hint: Remember the equilibrium expression and Le Chatelier’s Principle.
A reaction system at equilibrium has the following concentrations: [N2] = 0.2 M, [H2] = 0.6 M, [NH3] = 0.4 M. If the pressure is decreased, describe the shift in equilibrium.
💡 Hint: Consider how shifts are influenced by changes in pressure.
