+ Calculating Equilibrium Constants
The equilibrium constant, K, of a reaction at a
particular temperature is determined by the
concentrations or pressures of the reactants and
products at equilibrium.
For a gaseous reaction with the general form
aA+bB cC + dD
the Ke and K, expressions are given by
Kc =
[CD]
[A]ª[B]
(Pc) (Pb)d
(PA)" (PB)
K₂
The subscript c or p indicates whether K is
expressed in terms of concentrations or
pressures. Equilibrium-constant expressions do

The following reaction was performed in a sealed vessel at 730 °C:
H₂(g) + I2(g) 2HI(g)
Initially, only H₂ and I2 were present at concentrations of [H₂] = 4.00M and [I2] = 3.00M. The
equilibrium concentration of I2 is 0.0900 M. What is the equilibrium constant, Ke, for the reaction at this
temperature?
Express your answer numerically.
