For the denitrification [microbiological conversion of nitrite/nitrate (N-containing contaminants) to nitrogen gas (harmless end product)] to be more effective, an external carbon source (e.g., methanol) is frequently added for denitrifiers (denitrifying microorganisms) during the reaction. The following chemical reaction is for when methanol is added for this purpose. Calculate how much (concentration) of methanol (in mg/L) needs to be added to completely convert 30 mg/L of NO3--N to N2 gas. 0.1667 CH3OH + 0.1343 NO3- + 0.1343 H+ ↔ 0.0143 C5H7O2N + 0.06 N2 + 0.3505 H2O + 0.0952 CO2

The initial concentrations of four species involved in an equilibrium are: [Cl2] = 1.40 M, [HCl] = 0.100 M, [O2] = 0.300 M and [H2O] = 0.500 M. Is the reaction at equilibrium? If not, in what direction must the reaction shift for the equilibrium to be reached? Set up Kc in terms of the initial amounts and x as done in class. Do not try to solve for x. Set it up so x is positive. 4 HCl(g) + O2(g) <====> 2 Cl2(g) + 2 H2O(g) Kc = 52 At equil? ______ Direction? _______ Expression ____________
