Quick explanation
Construct Kc expressions for homogeneous equilibria
- This point belongs to Chemical equilibria, Le Chatelier's principle and Kc, especially Equilibrium constant Kc.
- You need to be able to construct Kc expressions for homogeneous equilibria.
- The key ideas to know are Kc.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Equilibrium constant Kc to exam-style questions, flashcards, and revision notes for Chemical equilibria, Le Chatelier's principle and Kc.
Quick student answer
Which of the following expressions correctly represents the equilibrium constant Kc for the reaction: 2A(g) + B(g) ⇌ 3C(g)?
Direct answer
A) Kc = [C]^3 / ([A]^2[B])
Key terms
- Equilibrium constant (Kc): A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.
- Homogeneous equilibrium: An equilibrium in which all reactants and products are in the same phase, typically gaseous or aqueous.
Common trap
Incorrect Kc expression: Always ensure that the Kc expression reflects the stoichiometry of the balanced equation.
