4) FeO(s)+H2(g)Fe(s)+H2O(g) G0T=162008.5T(J) a) Does reaction spontenously ocur at 1000K ? If doesn't, at which temperature it occurs spontenously? ( H and S0 would be assumed as constant) b) Find the reaction equilibrium constant for 1000K. What should be H2 partial pressure to occur at this temperature? (Partial pressure of H2O would be taken as Iatm ) 3) Calculate the reaction heat of formation of PbO from Pb and O2 at rxn temperatures of 500K and 800K seperately (using below reactions).
