Challenge Problems
Push your limits with advanced challenges
A reaction A + 2B ⇌ C reaches equilibrium with Kp = 4 at a certain temperature. If the initial concentration of A is 1 M and B is 2 M, find the equilibrium concentrations of A, B, and C.
💡 Hint: Define changes in concentrations with a variable and express Kp accordingly.
Given: ΔG0 = -200 kJ/mol for a reaction at 298 K. Calculate Kp using the relationship ΔG0 = -RT ln Kp.
💡 Hint: Remember to use the appropriate units in your calculations and convert ΔG0 accordingly.
