WebChemical reactions can be “coupled” together if they share intermediates. In this case, the overall Gibbs Free Energy change is simply the sum of the ∆ G values for each reaction. Therefore, an unfavorable reaction (positive ∆ G1) can be driven by a second, highly favorable reaction (negative ∆ G2 where the magnitude of ∆ G2 > magnitude of ∆ G1 ). WebThe term ‘coupling reaction’ refers to the class of organic reactions that involve the joining of two chemical species (usually with the help of a metal catalyst). An important type of …
