1.

As an EPA scientist studying catalytic converters and urban smog, you want to find Kc for the following reaction: 2 NO2 (g) ⇋ N2(g) + 2 O2(g) Kc = ??

Use the following data to find the unknown Kc:

1/2 N2 (g) + 1/2 O2 (g) ⇋ NO (g) Kc = 0.004

2NO2 (g) ⇋ 2NO (g) + O2 (g) Kc = 0.069

2. A chemical reaction between X2 and Y2 produces XY. All compounds are in a gaseous state. Consider that you have the following mixture of species in your reaction vessel at a given time:

X2 : 3 molecules

Y2 : 10 molecules

XY : 38 molecules

Calculate the equilibrium constant for the balanced reaction between one mole of each reagent.

3.

Given the two reactions

  1. H2S⇌HS−+H+,   K1 = 8.96×10−8, and
  2. HS−⇌S2−+H+,   K2 = 2.34×10−20,

what is the equilibrium constant Kfinal for the following reaction?

S2−+2H+⇌H2S
