Hello, let me break this down for you! :)
A is your energy of your reactants, B is your activation energy, so the total value could be found from B-Y. C is the value of your energy of your products. X is your delta H value. So in this, your products are higher energy than the reactants, so H is + and e2-E1 is positive so E2 >E1
Therefore your answers would just be <span>E2 > E1 and
</span><span>Hrxn<span> is positive.
Hope this helps! If you have any other questions or need further explanation just let me know! :)
