Problem- Please help me by showing the work and the answer, because I'm not understanding the material. Thanks.

Part A 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=7.80 If only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2 remains at equilibrium? Express your answer with the appropriate units.

Part B

Consider the reaction

CO(g)+NH3(g)?HCONH2(g), Kc=0.890

If a reaction vessel initially contains only CO and NH3 at concentrations of 1.00 Mand 2.00 M, respectively, what will the concentration of HCONH2 be at equilibrium?

State your solution with the appropriate units.
