So just to clarify, Exergonic and endergonic refer to Gibb's free energy whereas exothermic and endothermic only have to do with heat?

[Chem_Mod]

Endergonic/Exergonic refer to Gibbs Free Energy.
Endothermic/Exothermic refer to enthalpy.

[Rachel Lipman]

Yes. Remember in regards to the graphs. It helps!

[Kristen_Power_1C]

I find it helpful to remember the whole exergonic thing by thinking exerGonic -> G(ibbs free energy)! I don't know if anyone would find this useful but it sure helps me keep the terms straight :)

[diangelosoriano]

How do we compare these terms to graphs / visually?

[Jaewoo Jo 2L]

yeah, the first 2 terms are for gibbs and the later 2 are for heat.

[Katie Phan 1K]

Yes!

[Sabine Salvucci 2E]

How do we compare these terms to graphs / visually?

Hello! For reactions that are endothermic/endergonic, there will be more energy on the products side of the reaction and for reactions that are exothermic/exergonic, there will be more energy on the reactants side.

Here’s a graph of the two: https://chembossenergy.weebly.com/uploa ... 8_orig.gif

Hope this helps!

[Brenda Silva 1B]

Yes, exergonic and endergonic refer to Gibb's free energy whereas exothermic and endothermic refer to heat

[Taylor Newville 1C]

Endergonic and exergonic refer to changes in free energy (delta G). Endothermic and exothermic refer to changes in internal energy of molecules, measured as heat given off or taken up (delta H).

[Nick P 3D]

Endergonic or exergonic refer to gibbs free energy, while endothermic or exothermic refer to enthalpy.

[Ansh Patel 2I]

Hi! Yes you're right, exergonic/endergonic refer to Gibbs Free Energy while exothermic/endothermic refer to enthalpy.

[Michelle Nguyen 3F]

Yes!! Endergonic and exergonic refer to Gibbs Free Energy while endothermic and exothermic refer to enthalpy.

[Matlynn Giles 2E]

ender and exer for gibbs. endo and exo is for enthalpy
