Problem

At a temperature of 60 °C, the vapor pressure of water is 0.196 atm. What is the value of the equilibrium constant KP for the transformation at 60 °C?
H2 O(l) ⇌ H2 O(g)

Solution

Recall: The equilibrium constant is the ratio of the pressure or concentration of products and reactants, with each compound being raised to a power equivalent to the stoichiometric coefficient in the chemical equation.

For the reaction aA + bB ⇌ cC + dD, the equilibrium constant is:

where Kp is used for pressures and Kc is used for concentrations.
