Challenge Problems
Push your limits with advanced challenges
For the reaction SO2(g) + O2(g) ⇌ 2SO3(g) with Kc of 1000 at 1000 K, predict how Kc might change if the temperature is increased to 1200 K if it's exothermic.
💡 Hint: Think about the heat changes related to Kc.
For the equilibrium 4H2(g) + 2O2(g) ⇌ 4H2O(g), if Kc is found to be 0.01 at 298 K, discuss what this implies regarding the concentration of products compared to reactants.
💡 Hint: Visualize the proportions of each species present at equilibrium.
