Close Problem Tutored Practice Problem 15.3.2 COUNTS TOWARDS GRADE Use an /CE table to calculate K A mixture of CO and Cl, is allowed to react at 585 K CO(g) + Cl2(g) cOC2(g) The initial concentration of the reactants are [cO] = 0.3050 M and [Cl2] = 0.3390 M. After the system reaches equilibrium, it is found that the Ch concentration has decreased to 0.0659 M. Based on these data, determine the value of the equilibrium constant, K, for this reaction. K = Check & Submit Answer Show Approach

Answer 1

The equilibrium concentrations (E) is calculated by adding change in concentration (C) with initial concentration (I)

co + Cl - Coch 0. 3050m 0.3390 m c -0.27316 -0.27310 +0.273160 Eq. concentration of Cl₂ = 0.0659 m change in one of ch =0.3390 m 0.0659 0.2731 m I This will be the change in concentration of co also M 0.0319 0.0659 0.273110 [cocha 2 Equilibrium constant ka [co] [cl2] plug in E values K = 0.273100 - 129.91 (0.0319) (0.0659)
