Define “Kc”
A constant which indicates the equilibrium position. Tells to what extent will the reaction proceed or not
What else does Kc indicate again?
The equilibrium position
What is the simple form of the Kc expression?
products/reactants
What is the true expression of Kc?
Kc = [C]c[D]d/[A]a[B]b
![<p>Kc = [C]c[D]d/[A]a[B]b</p>](https://assets.knowt.com/user-attachments/7a5d22fe-0dd9-4108-a136-c95aae32b24f.png)
What does a Kc value <0.001 indicate?
Reactants are EXCESSIVELY favoured
More reactants are produced
What does a Kc value of >1000 indicate?
Products are EXCESSIVELY favoured
More products are produced
Does Kc have units or no units?
NO UNITS
Are solids (s) included or excluded in Kc calculations?
Excluded
Define the reaction quotient (Q)
Its expression is equivalent to Kc. However, it indicates whatever point of the reaction the substances are
What differentiates Q from Kc?
It indicates wherever the point of the reaction the substances reacting are, rather than the actual equilibrium point
