Phosphorus pentachloride is formed when phosphorus trichloride and chlorine react. PCl3(g) + Cl2(g) ⇌ PCl5(g) The equilibrium constant for the reaction is KC = 38.0 at 233 °C. If 0.510 mol of phosphorus trichloride is added to 0.238 mol of chlorine in a 1.11-L reaction vessel at this temperature, what is the equilibrium concentration (in mol/L) of phosphorus pentachloride? Report your answer to THREE significant figures.

Balance the chemical reaction equation P4(s)+Cl2(g)→PCl5(g) Enter the coefficients in order, separated by commas (e.g., 1,2,3). View Available Hint(s) 1,10,4 The balanced equation is P4(s)+10Cl2(g)→4PCl5(g) Calculations involving a limiting reactant Now consider a situation in which 28.0 g of P4 is added to 53.0 g of Cl2, and a chemical reaction occurs. To identify the limiting reactant, you will need to perform two separate calculations: Calculate the number of moles of PCl5 that can be produced from 28.0 g of...

In the reaction below, what volume of PCl5(g) will be produced by the reaction of 18.9 L of chlorine gas with excess phosphorus (P4) if all gas volumes are measured at STP? P4(g) + Cl2(g) => PCl5(g)(unbalanced) Enter your answer with two decimal places and no units. The answer should be 7.56, but I keep getting 6.92. Balanced P4 + 10Cl2 ----> 4PCl5 1 atm * 18.9L = n (.0821)*(298) 0.7725*(4/10)*22.4 =6.92 , I multiplied it times 22.4 because its...
