Question

Areactions with a positive delta g, ii. such as those in which two amino-acids are joined together to form a peptide bond, by themselves create order in the universe, iii. and therefore cannot occur spontaneously.

Answer 1

The question seems to be incomplete and vague as the requirement of the answer has not been given. So, I am giving an assumed answer.

The correct answer could be - Energetically unfavourable reaction.

An "Energetically unfavourable reaction" is a kind of reaction in which the delta G is positive and it occurs when 2 amino acids will be joined together in order to form a peptide bond. They create order by themselves in the universe and so they cannot occur spontaneously.

In contrast, the "Energetically favourable reactions" have a negative delta G and they create a disorder to the system in which they exist by decreasing its free-energy.
