1 Review | Constants | Periodic TableThe equilibrium constant, K, of a reaction at a particular temperature is determined by the concentrations orpressures of the reactants and products at equilibrium.For a gaseous reaction with the general form• Part AaA + bB eC+ dDPhosgene (carbonyl chloride), COC2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. Phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures:the Ke and Kp expressions are given byCo(g) + Cla (g) = cOCk (g)K.Carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 463 °C . At equilibrium, the concentrations were measured and the following results obtained:Kp(P(A)Partial Pressure(atm)GasCO0.890The subscript c or p indicates whether K is expressed in terms of concentrations or pressures. Equilibrium-constant expressions do not include a term for any pure solids or liquids that may be involved since theircomposition does not change throughout the reaction. The standard state of a pure substance is the puresubstance itself, and although the quantity may change the sample remain pure. The constant value isincorporated into the value of K, and does not need to be accounted for separately.1.27cocl0.120What is the equilibrium constant, Kp. of this reaction?Express your answer numerically.• View Available Hint(s)Templates Symbols undo redio teset keyboard shortcuts HelpKp = 0.144SubmitPrevlous AnawereX Incorrect; Try Again; 3 attempts remainingDeriving concentrations from dataIn Part A, you were given the equilibrium pressures, which could be plugged directly into the formula for K.
