If the pH of the matrix is 7.7, what is the pH of the intermembrane space if the $\Delta$G for transport of H⁺ is 20 kJ/mol at 37$\degree$C with $\Delta$$\Psi$ = 170 mV?

Question

The Gibbs free energy change ($\Delta G$) for the transport of protons is related to the pH difference and the membrane potential ($\Delta \Psi$) by the equation: $\Delta G = 2.303RT(\Delta pH) + F\Delta \Psi$. Solving for $\Delta pH$ using the given values ($\Delta G = 20 \text{ kJ/mol}$, $\Delta \Psi = 170 \text{ mV}$, $T = 310 \text{ K}$), we find that the pH of the intermembrane space is 7.1.
