Challenge Problems
Push your limits with challenges.
Question 1
Given a reaction at equilibrium with Kc = 2.0 and initial concentrations of A = 1.0 M, and B = 1.0 M, how can you find the equilibrium concentrations of A and B?
💡 Hint: Keep in mind the stoichiometry of the reaction.
Question 2
For the reaction 2NO(g) + O2(g) ⇌ 2NO2(g), given initial concentrations and an equilibrium constant of 58.4, how would you find the amount of NO2 formed?
💡 Hint: Use an ICE table to organize your data.
