Answer: Kp = Kc(RT)^Δn.
- A Kp = Kc always
- B Kp = Kc(RT)^Δn
- C Kc = Kp(RT)^Δn
- D Kp = Kc/RT
Correct answer: B. Kp = Kc(RT)^Δn
Explanation: Kp = Kc(RT)^Δn, where Δn is the change in moles of gas, R is gas constant, T is temperature in K.
As the reaction proceeds, reactant concentration falls and product concentration rises until both level off at equilibrium.
Concept context
When forward and reverse reaction rates are equal, equilibrium is reached. Learn about Kc, Kp, Le Chatelier's principle, and acid-base equilibria, including pH, buffer solutions, and solubility product.
