The equilibrium constant, Kc, for the following reaction is1.05×10-3 at 446 K. PCl5(g) PCl3(g) + Cl2(g) When a sufficientlylarge sample of PCl5(g) is introduced into an evacuated vessel at446 K, the equilibrium concentration of Cl2(g) is found to be 0.498M. Calculate the concentration of PCl5 in the equilibrium mixture.____M_______________________________________________________________________________________________________________A student ran the following reaction in the laboratory at 689 K:N2(g) + 3H2(g) 2NH3(g) When she introduced 4.06×10-2 moles of N2(g)and 5.20×10-2 moles of H2(g) into a 1.00 liter container, she foundthe equilibrium concentration of H2(g) to be 5.00×10-2 M.
