6th edition question from book

Postby Riya Shah 4H » Tue Jan 22, 2019 12:12 pm

Consider the equilibrium 3 NH3(g) + 5 O2(g) (equilibrium sign) 4 NO(g) + 6 H2O(g).
(a) What happens to the partial pressure of NH3 when the partial pressure of NO is increased?
(b) Does the partial pressure of O2 decrease when the partial pressure of NH3 is decreased?

Can someone please help me with the b part?
Does decreasing the pressure favor the side with more moles of gas?

By increasing the partial pressure of NH3 you are in essence just increasing the reactants side. As seen in Le Chatelier's principle, the products would then increase to counter act this shift and the partial pressure of O2 would in fact decrease. I think you may be confusing this with the system being compressed as a whole where the stoichiometric moles of gas would then become a factor. Hope this helped!
