Which of the following has AG°f= 0 at 25°C? There may be more than one correct answer so check each answer that is correct.
H20(g)
O3(g)
Na(s)
O(g)
H2O(l)
Homework Answers
Species in their standard states have dG0 = 0 at 25 C
only Na(s) is in standard state which has zero dG0 value. Elemental O(g) is not standard form .dG0 = 0 for O2 gas.But that is not present in the given set. Hence
Answer
Na(s)

The
correct answer is the 3rd one.
NO3- has more charges and thus is more unstable than water, so
wouldn't it be more likely for it to accept H+, making it a
stronger Bronsted-Lowry base compared to H20? (aka, Why is water
better at accepting H+ than NO3-?)
F- should be the strongest Bronsted-lowry base because HF is a
weak acid and thus its CB is more unstable (that's why it doens't
really want to donate its H+) -> an...
