Question

Consider the reaction H2O(g)+Cl2O(g)=2HClO(g). At equilibrium,the concentrations of the different species:[H2O]=0.077M,[Cl2O]=0.077M,[HClO]=0.023M. What is the equilibrium constant for the reaction at this temperature?

Choices: 0.089, 0.26, 3.9, or 11

Answer 1

The equilibrium constant K : 0.089

Further explanation

Given

Reaction

H₂O(g)+Cl₂O(g)⇔2HClO(g)

[H2O]=0.077M,[Cl2O]=0.077M,[HClO]=0.023M

Required

the equilibrium constant

Solution

The equilibrium constant or Kc is the value of the concentration product in the equilibrium state of the substance in the right segment divided by the product of the substance in the left section, each of which has a reaction coefficient raised

`\tt K=([HClO]^2)/([H_2O][Cl_2O])\\\\K=(0.023^2)/(0.077* 0.077)\\\\K=0.08922`
