Free Energy and Reaction Direction

Free energy and reaction direction are linked in chemical equilibrium. A free energy change, ΔG, shows the driving force for a process. When ΔG is negative, the process is driven forward. When ΔG is positive, the reverse direction is favored. When ΔG is zero, the forward and reverse driving forces are equal, and the system i...

特定反应的自由能变化，即ΔG，等于标准自由能与RT乘以产物浓度与反应物浓度之比的自然对数的总和。
