Challenge Problems
Push your limits with advanced challenges
A reaction's rate constant was measured at different temperatures, leading to a Kc of 25 at 300 K. If this reaction is exothermic, predict the Kc values at 350 K. Explain your reasoning.
💡 Hint: Remember how heat influences reaction direction.
In a laboratory reaction, an experiment shows that at equilibrium, [A] = 0.3 M, [B] = 0.4 M, and [C] = 0.5 M for the reaction A + B ⇌ C. Calculate Kc for this reaction and interpret its significance.
💡 Hint: Consider how you derive Kc from the equilibrium concentrations.
