Chemical Equilibrium: Kc, Kp and Quantitative Applications
Students will be introduced to the concept of reversible reactions and understand that equilibrium is a dynamic state where forward and reverse reactions occur at equal rates.
Key Questions
- Write Kc and Kp expressions for a heterogeneous equilibrium and calculate their numerical values from equilibrium data, converting between Kc and Kp using Kp = Kc(RT)^Δn.
- Predict and quantitatively justify the effect of a temperature change on the value of K for an exothermic reaction, distinguishing this thermodynamic effect from the kinetic effect on reaction rate.
- Evaluate the industrial conditions chosen for the Haber process by applying both Kp calculations and the Arrhenius equation, resolving the conflict between equilibrium yield and rate of attainment.
