What happens to the concentration of
NO(g) when the total pressure on the equilibrium reaction
3NO2(g) + H2O <---> 2HNO3(aq) + NO(g)
is increased (by compression)?
1. increases
2. remains the same
3. decreases
4. Unable to determine
2 answers
It increases.
In a gaseous equilibrium (I assume the H2O is liquid) increases pressure shifts the equilibrium to the side with fewer mols of gas.
