Equilibrium constant (Kp) for Homogeneous Systems (A Level only) (AQA A-Level Chemistry): Flashcards

Equilibrium position in terms of partial pressures

Constant at given temperature, changes if temp altered

Ratio of moles of A to total moles of all gases

$x_A = \frac{n_A}{n_A + n_B + n_C}$

1

$p_A = x_A \times \text{total pressure}$

$K_p = \frac{(p_C)^c \times (p_D)^d}{(p_A)^a \times (p_B)^b}$

Partial pressures of the gases

Coefficients from the balanced equation
