Challenge Problems
Push your limits with challenges.
Question 1
Consider the equilibrium N2(g) + 3H2(g) ⇌ 2NH3(g) with ΔH = -92 kJ. Predict how K changes as temperature is raised from 400°C to 600°C.
💡 Hint: Review how exothermic reactions behave with increasing temperatures.
Question 2
Given ΔG° = -10.2 kJ for the reaction CO(g) + 2H2(g) ⇌ CH3OH(g) at 298 K, calculate the predicted value of K.
💡 Hint: Use the connection of ΔG with K.
