Equilibrium Homework

Homework, please solve the following problems: 1. For an equilibrium reaction, what effect does reversing the reactants and products have on the value of the equilibrium constant? 2. Which equilibriums are homogeneous, and which are heterogeneous? Homogeneous means the same state, such as all gases. a. 2HF(g)⇌H2(g)+F2(g) b. C(s)+2H2(g)⇌CH4(g) c. H2C=CH2(g)+H2(g)⇌C2H6(g) d. 2Hg(l)+O2(g)⇌2HgO(s) 3. Classify each equilibrium system as either homogeneous or heterogeneous. a. NH4CO2NH2(s)⇌2NH3(g)+CO2(g) b. C(s)+O2(g)⇌CO2(g) c. 2Mg(s)+O2(g)⇌2MgO(s) d. AgCl(s)⇌Ag+(aq)+Cl−(aq) 4. Write the equilibrium constant expressions for K for each reaction. a. CO(g)+H2O(g)⇌CO2(g)+H2(g) b. PCl3(g)+Cl2(g)⇌PCl5(g) c. 2O3(g)⇌3O2(g) 5. Write the equilibrium constant expressions for K as appropriate for each reaction. a. 2NO(g)+O2(g)⇌2NO2(g) b. 12H2(g)+12I2(g)⇌HI(g) c. cis−stilbene(soln)⇌trans−silbene(soln)
