![Reaction energetics How are the standard free energy changes of biomolecular reactions determined? Consider the same bidirectional reaction as in the previous slide: Under equilibrium, Starting condition (T 298.15 K) =-(2.3)(0.002)(298.15 )logio (17) [A]0 = 2 M =-1.7 kcal/mol [a]o = 1 M Under equilibrium, Km = [A]/[a]s 17 A] and [a] can also be determined: [A] + [a] = [A]o + [alo = 3 [A]/[a] = 17 Solve equations above to get [A] = ? M. [a] = ? M](http://img.homeworklib.com/questions/4d531570-c633-11ea-ab44-079c647594da.png?x-oss-process=image/resize,w_560)
