Challenge Problems
Push your limits with advanced challenges
Given the reaction N2 + 3H2 ⇌ 2NH3, if 0.9 moles of NH3 are produced in a 1-liter container and the initial moles of N2 and H2 were 1.5 and 4.5 respectively, calculate the equilibrium concentrations of all species.
💡 Hint: Think about how much each species changes at equilibrium.
If the equilibrium constant K for A + B ⇌ C is 5.0 at a certain temperature, and if the initial concentrations are [A] = 1 M and [B] = 1 M, what will be the equilibrium concentrations?
💡 Hint: Use algebra to express the changes in terms of x.
