[Unit 6.4] | The Equilibrium Constant

Question 1

What is the expression for an Eq Constant? (Concentration)

Answer 1

Example: 2R1 + 2R2 -> P1 + 3P2

[P1]¹ x [P2]³ /
[R1]² x [R2]²

• R = Reactant
• P = Product
• [x] = Concentration of x
• x² = 2 moles of x

Question 2

What does eqm mean?

Answer 2

Mixture has reached equilibrium: Equilibrium mixture.

Question 3

What do the different equilibrium constant values mean?

Answer 3

Small Kc: Equilibrium is on the left
Kc of 1: Equilibrium is in the middle
Large Kc: Equilibrium is on the right
