Chapter 6: Q. 10 P (page 169)

Which reaction is more energetically favored, one with ΔGo= - 44 or one with ΔGo= +44 ?

Short Answer

Expert verified

The reaction with ΔGo= - 44 is energetically more favorable.

Step by step solution

01

Spontaneous reaction

Reactions that proceed without an external energy supply are called a spontaneous reaction.

For a reaction to be spontaneous, it needs to have a negative value of Gibbs free energy.

Also,for the reaction to be spontaneous, the value ofΔSo needs to be positive.

02

Energetically favored reaction

The reaction with a negative ΔGovalue is energetically favorable. In the above two cases, one value is positive and the other is negative. So the negative value of Gibbs free energy indicates that the reaction is energetically favored.

Hence, the reaction with role="math" localid="1649937296710" ΔGo= - 44 is energetically more favorable.
