Consider the reaction shown below. PbCO3(s) PbO(s) + CO2(g) Calculate the equilibrium pressure of CO2 in the system at the following temperatures. (a) 210°C atm = _______ atm (b) 480°C atm = _______ atm Note: To find the value of the equilibrium constant at each temperature you must first find the value of G0 at each temperature by using the equation G0 = H0 - TS0. For this reaction the values are H0 = +88.3 kJ/mol and S0= 151.3 J/mol*K
