Which of the following indicates a reaction with a positive ΔG? A. endergonic, spontaneous B. endergonic, not spontaneous C. exe
shtirl [24]

Answer: B. endergonic, not spontaneous

Explanation:

Endergonic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and  \Delta H for the reaction comes out to be positive.

The Gibbs equation is:

\Delta G=\Delta H-T\Delta S

\Delta G= Gibb's free energy change

\Delta H = enthalpy change

T = temperature

\Delta S = entropy change

A reaction is non spontaneous when \Delta G= Gibb's free energy change is positive

+ve=\Delta H-T(-ve)

+ve=\Delta H+ve

\Delta H=+ve

Thus the reaction has to be endergonic.

emmasim [6.3K]

Answer:

In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. The term metamer was formerly used for the same concept.
