Equilibrium constant Kp for homogeneous systems

Question 1

What is Kp?

Answer 1

The equilibrium constant used for gaseous equilibria. All reactants and products must be in gaseous state

Question 2

What is the formula for partial pressure?

Answer 2

Partial pressure of A = (Moles of A/ Total Moles) * Total pressure

Question 3

How to calculate Kp?

Answer 3

2A(g) + 3B(g) -> Y(g) + 2Z(g)

Kp = (pY)(p^2 Z)/(p^2A)(p^3B)
