Calculate the equilibrium constant for the reaction below if a tank was found to contain 0.107 M O2, 0.00604 M SO3, and 0.00270 M SO2. 2 SO3(g) ↔ 2 SO2(g) + O2(g)

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
