Ppt Question

Postby Jessica Chen 2C » Sat Mar 14, 2020 10:04 pm

For the question on slide 5 of the final review PowerPoint, why do we only use the delta G for PCl5 and PCl3 when calculating the delta G of the reaction?

This is because the standard gibbs free energy for Cl2 is 0 as diatomic molecules are already in their standard state. Thus when calculating the delta G of the reaction we exclude the delta G for Cl2 since it is 0.

I think it might be because the gibbs free energy of formation for Cl2 is 0, since it's already in its most stable form.
