1. ### Consider the following reaction:  CS2(g) + 4H2(g) ↔ CH4(g) + 2H2S(g) ?

Kp=Kc(RT)^Δn where Δn = moles of gaseous products - moles of gaseous reactants.  Here, Δn = 3 - 5= -2 Kp = 0.27 [(0.08206)(1173K)]^-2 = 2.9X10^-5

7. ### A 92.7−g sample of dinitrogen monoxide is confined in a 3.94−L vessel. What is the pressure (in atm) at 123° C ?

Supposing the N2O does not decompose: P = nRT / V = (92.7 g N2O / (44.0128 g N2O/mol)) x (0.082057366 L atm/ K mol) x (123 + 273) K / (3.94 L) = 17.4 atm

8. ### If 1.68 × 10−3 mol of argon occupies a 67.3−mL container at 32° C , what is the pressure (in torr)?

P = nRT / V = (1.68 × 10^−3 mol) x (62.36367 L torr/ K  mol) x (32 + 273) K / (0.0673 L) = 475 torr
