# Partial Pressure

If one starts with pure NO2(g) at a pressure of 0.500 atm, the total pressure inside the reaction vessel when 2NO2(g) = 2NO(g) + O2(g) reaches equilibrium is 0.674 atm. Calculate the equilibrium partial pressure of NO2.

#### Solution Preview

Assume that the reaction starts out with 1 mole of NO2. This assumption can be made since the ratio of the end products to initial product is not influenced by the quantity of initial product. Therefore the partial pressure (a ratio) will not be ...

#### Solution Summary

This solution looks at the equilibrium partial pressure of a reaction in a vessel.
