Question

3/For a particular reaction, DeltaH = -32kJ and DeltaS = -98J/K.Assume that deltaH and deltaS do not vary with temperature. (a) atwhat temperature will the reaction have deltaG=0? (b) iftemperature is increased from that in part (a), will the reactionbe spontaneous or non-spntaneous?

4/The equilibrium constant (Kp) for the reaction H2(g) + CO2(g)=> H2O(g) + CO(g) is 4.40 at 2000K. (a) Calculate deltaGo forthe reaction. (b) calculate deltaG for the reaction when thepartial pressures are PH2 = 0.25 atm, PCO2 = 0.78 atm, PH2O=0.66atm and PCO=1.20 atm and predict the direction of the reaction
