Question- Phosphorus pentachloride decomposes according to the chemical equation PCl5(g) = PCl3(g) + Cl2(g). Kc= 1.80 at 250degree Celsius. A 0.212 mol sample of PCl5(g) is injected into an empty 3.00 L reaction vessel held at 250 °C. Calculate the concentrations of
PCl5(g) and PCl3(g) at equilibrium.
PCl5 = ______number of M
PCl3= ______ number of M
After filtering off this precipitate, the pH is adjusted to 8 and H2S is again added; no precipitate forms. No precipitate forms upon addition of (NH4)2HPO4. The remaining solution shows a yellow color in a flame test. Based on these observations,..
