Could anyone help me with this question?
And would the more stable isomer be E because the Gibbs free energy value is minus? Why does a minus free energy make it more stable if this is the case??

Sorry you've not had any responses about this. :frown: Are you sure you've posted in the right place? :smile: Here's a link to our subject forum which should help get you more responses if you post there. :redface:

You can also find the Exam Thread list for A-levels here and GCSE here. :dumbells:


Just quoting in Puddles the Monkey so she can move the thread if needed :h:

If deltaG is negative the change is 'spontaneous'. This means E is more stable.

But why does a negative free energy value mean it's stable? That's what I don't get.

Would you agree that E is more stable than Z based only on the delta H values?

Yes cos E is more exothermic?
