Bromine monochloride is synthesized using the reaction Br₂(g) + Cl₂ (g) 2 BrCl(g) Kp = 1.1 x 104 at 150 K A 209.0 L flask initially contains 0.911 kg of Br₂ and 1.070 kg of Cl₂. Calculate the mass of BrCl, in grams, that is present in the reaction mixture at equilibrium. Assume ideal gas behavior.

Consider the following reaction at a certain temperature: 4 Fe(s) + 3 O2(g)→ 2 Fe203(s) An equilibrium mixture contains 1.2 mol Fe, 0.00090 mol O2, and 2.0 mol Fez03 all in a 2.0-L container. Calculate the value of K for this reaction. K =

A chemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2NO(g) +  Cl2(g)⇌ 2NOCl(g) Kp=2.x10^−1   He fills a reaction vessel at this temperature with 10.atm of nitrogen monoxide gas and 12.atm of chlorine gas. Use this data to answer the questions in the table below. Can you predict the equilibrium pressure of NOCl, yes or no? If yes, then what is the equilibrium pressure of NOCl? Round your answer to 1 significant digit.

At a certain temperature, the equilibrium constant, K., is 0.00572 for the reaction Cl,(g) = 2 Cl(g) A. If 2.77 g Cl, is placed in a 2.50 L flask at this temperature, what are the equilibrium concentrations of Cl, and Cl? [CI,] = M [CI] = M B. Following the establishment of equilibrium in part A, the volume of the flask is suddenly increased to 5.00 L while the temperature is held constant. What are the new equilibrium concentrations of Cl, and Cl? [Cl,] = M [CI] = M C. Following the establishment of equilibrium in part A, the volume of the flask is instead suddenly decreased to 1.0 L while the temperature is held constant. What are the new equilibrium concentrations of Cl, and CI? [Cl,] = M [CI] = M
