Consider the reaction. mc032-1.jpg at equilibrium, the concentrations of the different species are as follows. [h2o] = 0.077 m [cl2o] = 0.077 m [hclo] = 0.023 m what is the equilibrium constant for the reaction at this temperature?

The equilibrium constant is a value which represents the equilibrium of a reaction. It is a reaction quotient when the reaction reached equilibrium. If Keq is greater than 1, the mixture contains mostly the products. On the other hand, if Keq is less than 1, the mixture contains the reactants. It is calculated as follows: 2HClO = H2O + Cl2O

Keq = [H2O] x [Cl2O] / [HClO]^2
Keq = 0.077 x 0.077 / 0.023
Keq = 0.258

The answer should be vaporization 

The ratio is 3: 2. i.e. c.
