Name: __________________________________________ Date: ____________ WKST #15: Equilibrium Constant (40 points) Period: ___________ For each question below: Write the general K eq expression for the reaction Substitute in the concentrations for each of the reactants and products Solve for the value of K eq Determine if the forward or reverse reaction is favored 1. H 2 (g) + Br 2 (g) 2 HBr (g) The equilibrium concentrations are: [H 2 ] = 0.50 M [Br 2 ] = 0.25 M [HBr] = 0.85 M 2. 2 SO 3 (g) 2 SO 2 (g) + O 2 (g) The equilibrium concentrations are: [SO 3 ] = 0.015 M [SO 2 ] = 0.10 M [O 2 ] = 0.25 M 3. 2 CO (g) + O 2 (g) 2 CO 2 (g) The equilibrium concentrations are: [CO] = 0.065 M [O 2 ] = 0.0055 M [CO 2 ] = 0.0040 M 4. 6 NO (g) + 6 H 2 (g) 3 N 2 (g) + 6 H 2 O (g) The equilibrium concentrations are: [NO] = 0.10 M [H 2 ] = 0.50 M [N 2 ] = 0.30 M [H 2 O] = 0.30 M
