Challenge Problems
Push your limits with advanced challenges
In a reaction A + B ⇌ C, the equilibrium concentrations are [A] = 0.2M, [B] = 0.3M, and [C] = 0.4M. Calculate Kc.
💡 Hint: Use the given concentrations to compute Kc.
Consider the reaction 2D ⇌ E + F. If Kc = 9, determine the equilibrium concentrations if [E] = 0.5 M and [F] = 0.5 M.
💡 Hint: Reorganize the Kc expression to find the unknown concentration.
