What is the answer to this??? -2 ( 4x - 3y + 18)

Chemistry
The initial concentration for the compounds involved in the reaction shown were determined to be [ClF(g)] = 0.5789 mol/L, [F2(g)] = 0.5980 mol/L, [Cl2(g)] = 0.05037 mol/L. Calculate the value of the equilibrium constant (Kc) at 2500 K if the equilibrium concentration of F2(g) ...

Chemistry
Calculate the value of the equilibrium constant (Kc) for the reaction displayed if the following equilibrium concentration data were measured at 723.0 K: [N2(g)] = 2.936 mol/L, [H2(g)] = 2.933 mol/L, [NH3(g)] = 3.443 mol/L. N2(g)+3H2(g) = 2NH3(g)

Chemistry
Calculate the value of the equilibrium constant (Kc) for the reaction shown, if NO2(g) was found to be 95.54 % decomposed at 45.00 °C when its initial concentration was 5.725 mol/L. The initial concentration of the reaction products is 0 mol/L. 2NO2(g) = N2O4(g)

Chemistry
If the initial concentration of BrCl(g) is 4.680 mol/L, calculate the % of BrCl(g) left over after the reaction reaches equilibrium according to the balanced equation. The value of Kc at 500.0 K is 32.00. The initial concentration of the reaction products is 0 mol/L. 2BrCl(g...
