Use δg∘f values from appendix iib to calculate the equilibrium constants at 25 ∘c for each of the following reactions.
2no2(g)⇌n2o4(g)
32h2(g)+14p4(g)⇌ph3(g)

Ammonium perchlorate nh4clo4 is the solid rocket fuel used by the u.s. space shuttle. it reacts with itself to produce nitrogen gas n2 , chlorine gas cl2 , oxygen gas o2 , water h2o , and a great deal of energy. what mass of nitrogen gas is produced by the reaction of 2.1g of ammonium perchlorate?
