For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 bar for all species. For the reaction C,H,(g) + H,(g) =2CH,(g) the standard change in Gibbs free energy is AG = -32.8 kJ/mol. What is AG for this reaction at 298 K when the partial pressures are Pc,H, = 0.500 bar, PH, = 0.300 bar, and PCH, = 0.650 bar? AG = kJ/mol

the free energy for a reaction can be related to the equilibriumconstant through the formula below.K = e (-ΔG° / RT)Therefore if Kc for a reaction is known, Go can be determined, or vice versa. Furthermore, ifyou have the value for Go at two different temperatures, you can calculate H and S throughthe familiar equation for Gibbs energy below, since you have two unknowns but also twoequations.G = H – T SIn this lab you will be studying the solubility of borax (Na2B4O5(OH)4*8H2O), a slightly solublesodium salt, at two different temperatures. When solid borax is added to water, theequilibrium below is established.Na2B4O5(OH)4*8H2O (s) 2 Na+ (aq) + B4O5(OH)42- (aq) + 8 H2O(l)If you measure the concentrations for those substances that show up in the reaction quotient,then the Kc for the reaction at that temperature can be calculated. In this lab, theconcentration of borate ion (B4O5(OH)42-) in solution will be measured by titration with standardhydrochloric acid according to the…
