Question

The concentrations of reactants and products for a chemical reaction can be calculated if the equilibrium constant for the reaction and the starting concentration of reactants and/or products are known. Carbonyl fluoride, COF2. is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction 2COF2(g) CO2(g) + CF4(g), Kc = 7.50 If only COF2 is present initially at a concentration of 200 M. what concentration of COF2 remains at equilibrium? Express your answer with the appropriate units. Consider the reaction Co(g) + NH3(g) HCONH2(g), Kc = 0.670 If a reaction vessel initially contains only CO and NH3 at concentrations of 1.00 M and 200 M, respectively, what will the concentration of HCONH2 be at equilibrium? Express your answer with the appropriate units.

Explanation / Answer

2(2-x)-->x +x kc=x^2/2(2-x)=7.5 x^2=15(2-x) x^2+15x-30=0 x=1.787 So remaining COF2=2(2-x)=0.426 M
