[Catalist] Equilibrium and temperature

I think this song may help to straighten out misconceptions.

Hi Andrew - although outside of the ATAR course, http://www.chem1.com/acad/webtext/thermeq/TE5.html is pretty good at explaining the relationship between changes in Gibbs free energy and K. Also, https://aatishb.com/entropy/ uses sheep to explain entropy and it's AWESOME!

 

Enjoy the weekend :)

Dear chemistry teachers,

 

When a system is heated, both the forward and reverse reaction rates increase, “but the endothermic reaction increases more than the exothermic reaction. The endothermic reaction is always affected more by a temperature change than the exothermic reaction. This is true even when a system is cooled…” Chem for WA 2.

 

My question is why is the endothermic reaction rate always effected more than the exothermic rate? I cannot find an explanation in any of my texts, only a re-stating of this in various forms.

 

Thanks

 

Andrew
