Consider the following equilibrium system: \[ \mathrm{PCl}_{5}(\mathrm{~g}) \rightleftharpoons \mathrm{PCl}_{3}(\mathrm{~g})+\mathrm{Cl}_{2}(\mathrm{~g}) \] A 10.00 L evacuated flask is filled with 0.4150 mol \( \mathrm{PCl}_{5}(\mathrm{~g}) \) at \( \mathbf{2 9 7 . 4} \mathrm{K} \). The temperature is then raised to 501.7 K , where the decomposition of \( \mathrm{PCl}_{5} \) gas takes place to an appreciable extent. When equilibrium is established, the total pressure in the flask is 2.433 atm.

Câu 1: Giải tam giác Dạng 1: Cho tam giác ABC có \( \mathrm{AB}=5 \mathrm{~cm}, \mathrm{BC}=7 \mathrm{~cm}, \mathrm{AC}=6 \mathrm{~cm} \). Tính số đo các góc \( \mathrm{A}, \mathrm{B}, \mathrm{C} \).

Phosphorus pentachloride can dissociate into phosphorus trichloride and chlorine: \[ \mathrm{PCl}_{5}(\mathrm{~g}) \rightleftharpoons \mathrm{PCl}_{3}(\mathrm{~g})+\mathrm{Cl}_{2}(\mathrm{~g}) \] At \( 250^{\circ} \mathrm{C} \), the equilibrium constant in terms of pressures, Kp , for this dissociation reaction is 2.15 . (a) If 19.66 g of phosphorus pentachloride is placed in a \( 15.21-\mathrm{L} \) vessel and heated to \( 250^{\circ} \mathrm{C} \), what is the partial pressure of phosphorus trichloride when equilibrium is attained? (b) What fraction of phosphorus pentachloride is dissociated at equilibrium?
