Problem 19P
Guldberg and Waage proposed the definition of the equilibrium constant as a certain ratio of concentrations. What relationship allows us to use a particular ratio of partial pressures (for a gaseous reaction) to express an equilibrium constant? Explain.
ANSWER:
Solution 19P:
Here, we are going to show the relationship between the partial pressures (for a gaseous reaction) and an equilibrium constant.
Step 1:
Let us consider a general gaseous reaction
where a, b, c, and d are the stoichiometric coefficients, the equilibrium constant is
