In the text the equation δg = δg° + rt ln(q) was derived for gaseous reactions where the quantities in q were expressed in units of pressure. we also can use units of mol/l for the quantities in q—specifically for aqueous reactions. with this in mind, consider the reaction hf(aq) equilibrium reaction arrow h +(aq) + f −(aq) for which ka = 7.2 ✕ 10−4 at 25°c. calculate δg for the reaction under the following conditions at 25°c. based on the calculated δg values, in what direction will the reaction shift to reach equilibrium for each of the five sets of conditions?
