To calculate \(\Delta G\) and \(\Delta G^\circ\) for the reaction \(A + B \rightleftharpoons C + D\) at \(27^\circ C\) with \(K = 10^2\), we will follow these steps: ### Step 1: Calculate \(\Delta G\) At equilibrium, the change in Gibbs free energy (\(\Delta G\)) is equal to zero. Therefore: \[ \Delta G = 0 \, \text{(at equilibrium)} \] ...
