Challenge Problems
Push your limits with challenges.
Question 1
Given an equilibrium reaction where Kc = 0.05 and initial concentrations of reactants are unknown, determine the concentrations of all reactants and products at equilibrium if they started from 1 mol each.
💡 Hint: Use the ICE table method for incremental changes.
Question 2
Analyze a reaction with an equilibrium constant relationship where the temperature is changed and determine how the constant Kc would respond.
💡 Hint: Remember the endothermic vs. exothermic balance!
