    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??

    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?
