The equilibrium constant for the equation HNO3(aq) + H2O(l) = H, 0+ (aq) + NO2 (aq) is Kg = 5.6 x 10-4 M at 25.0 °C. Calculate the value of AGixn at 25.0 °C for nitrous acid when [NO2] = [H3O+] = [HNO2] = 1.00 M. AGixn = kJ/mol Will the acid spontaneously dissociate under these conditions? O no O yes Calculate the value of AGrxn for nitrous acid when [NO, ] = [H,O+] = 7.13 x 10- M and...
