Is Exergonic positive or negative?
A chemical reaction progresses only spontaneously when the Gibbs free energy decreases, in that case the ΔG is negative. In exergonic reactions the ΔG is negative and in endergonic reactions the ΔG is positive: exergon. endergon.
What is endergonic reaction in biology?
An endergonic reaction (such as photosynthesis) is a reaction that requires energy to be driven. … The activation energy for the reaction is typically larger than the overall energy of the exergonic reaction(1). Endergonic reactions are nonspontaneous.
