In physical chemistry, the standard state for a solution is 1 M. In biological systems, however, we define the standard state as 1 ✕ 10−7 M because the physiological pH is about 7. Consequently, the change in the standard Gibbs energy according to these two conventions will be different involving uptake or release of H+ ions, depending on which convention is used. We will therefore replace ΔrGo with ΔrGo', where the prime denotes that it is the standard Gibbs energy change for a biological process. (a) Consider the following reactions where x is a stoichiometric coefficient. (i) A + B → C + x H+ (ii) C + x H+ → A + B Derive a relation between ΔrGo and ΔrGo' for reaction (i), keeping in mind that ΔrG is the same for a process regardless of which convention is used.
