1, Carbon dioxide is heated to 2800 K at a constant pressure of 2 atm and dissociates to the following reaction: CO2 arrow CO+1/2O2 Determine the equilibrium composition where CO2, CO, and O2 are simultaneously present. Solution Let us consider the initial value concentration of CO 2 as x and at equllibirum it genetrated y conectration of CO. Initially CO 2 <----> CO + 1/2 O 2 Conectraion: x 0 0 At equllibrium CO 2 <----> CO + 1/2 O 2 Conectraion: x-y y y/2 Let K c be the equillibrium constant then K c = [x-y] / [y] [y/2] 1/2 calculate the value of and palce the value as in the concentration inequliibrium state .
