Thermodynamically Favorable

Postby Wasila Sun 2I » Thu Feb 18, 2021 7:12 pm

What does the term thermodynamically favorable mean? Is this just in reference to the Gibbs Free Energy value or is it something else?

A reaction is thermodynamically favorable when enthalpy decreases and entropy increases. This also means when the change in Gibbs Free energy is negative.

I think a reaction could still be thermodynamically favorable even if both enthalpy and entropy are increasing or if both are decreasing, as long as the Gibbs free energy is negative. If both are positive, then the reaction is thermodynamically favorable at higher temperatures, and if both are negative, the reaction is thermodynamically favorable at lower temperatures. I also think "spontaneous" means the same thing, though they might be slightly different.

Thermodynamically favorable means that the reaction/process does not require an input of energy to occur, meaning it occurs naturally. When gibbs free energy is negative, the process is thermodynamically favorable.

a reaction is spontaneous when ∆G = (-)

favorable or stable or spontaneous all imply the same thing: deltaG < 0 (negative)

When delta G is negative, it is considered to be thermodynamically favorable.

entropy tends to want more disorder while enthalpy wants less heat. These are conditions that would be favorable when analyzing entropy and enthalpy

The reaction is considered thermodynamically favorable when ΔG is negative

Typically something that is thermodynamically favorable are reactions that have a negative Gibb's Free Energy.

When delta G is negative, it's favorable because of spontaneity.

If gibbs free energy is negative the reaction is spontaneous and therefore thermodynamically favorable.

Being thermodynamically favorable means that the reaction is spontaneous, meaning that the reaction occurs naturally under certain conditions (for example, at a certain temperature). We can find out if a reaction is thermodynamically favorable by finding the ΔG of the reaction. A negative ΔG means that the reaction is spontaneous in the forward direction and thus is thermodynamically favorable.

Thermodynamically favorable is usually in reference to delta G or Gibbs free energy. The term means that delta g is negative so the reaction is spontaneous and the products are stable.

a rxn is thermodynamically favorable if the ∆G˙ is negative, and unfavorable if ∆G˙ is positive!

this same rule applies to molecules as well, meaning that a compound will be thermodynamically stable if the ∆G˙of formation is negative, and unstable if ∆G˙ of formation is positive

Thermodynamically Favorable just means that the gibbs free energy is negative

I think thermodynamically favorable just means spontaneous. Other things besides Gibbs Free Energy can be favored, such as a system doing less work or a system having higher entropy.

Thermodynamically favorable is is spontaneous and occurs when gibbs free energy is negative. When gibbs free energy is positive, the reaction is nonspontaneous.

Thermodynamically favorable is when delta G is negative, and the forward reaction is positive!

Thermodynamically favorable is when the reaction is spontaneous, which would thus mean that the Gibbs' free energy is negative. When the Gibbs' free energy is positive, the reaction is nonspontaneous and thus thermodynamically unfavorable.

Usually when delta G is negative, the reaction is thermodynamically favorable and spontaneous.

A reaction is thermodynamically favorable when deltaG is negative which means that the reaction is spontaneous. A spontaneous reaction means that it doesn't take external energy to make that reaction occur.

thermodynamically favorable = enthalpy decreases and entropy increases (negative dG)

A reaction is thermodynamically favorable when the delta G is negative. This also means that the reaction can occur spontaneously.

I agree with Tikva.

Additionally, if we think of a spontaneous process as a system that releases free energy (usually as heat) and moves to a lower, more thermodynamically stable energy state, then we can think of when ΔG < 0 or ΔG being negative as when the reaction is most thermodynamically favorable.

Why would you not want to be stable when you can be you know?

It refers to a negative Gibbs free energy value.

I would agree with what everyone else said. A reaction is thermodynamically favorable when delta G is < 0. The reaction will proceed in the forward direction spontaneously.

It is favorable when delta G is negative meaning it is spontaneous.
