Consider the endothermic reaction: N2O4(g) 2 NO2(g). Directly after increasing the pressure, what is the relationship between Q and Kc?

Consider the endothermic reaction: N2O4(g) 2 NO2(g)  For our equilibrium, Kc =4.6 * 10-3  under the current conditions. What does this imply for the concentrations of NO2 and N2O4?

The molality of a solution is defined as

What happens to the equation ΔH = ΔU + VΔp if the change in pressure is very small?    

A 1.536 sample of K2SO4 is dissolved in 20.0 g of water (Kf = -1.86oC/m)). The solution freezes at -2.07oC. What is the van’t Hoff factor, i, for this solution?

Calculate the volume of 0.500M stock of Fe3+solution you need to dilute with deionized water to prepare 80.0 mL of 0.0750M solution of Fe3+(aq).

Which substance would lower the freezing point of a solvent the most? 

In the calorimeter experiment that explores the combustion of a fuel, which part of the equation stays constant? ΔH =ΔU + VΔp

Consider the endothermic reaction: N2O4(colorless gas) 2 NO2(brown gas). Why does the color get paler after the pressure increases? 

The Haber process is exothermic. In which direction will the equilibrium be shifted by heating the reaction chamber with the bunsen burner? The reaction is: N2(g) + 3H2(g)  ⇌ 2NH3(g)
