Hi, I have been stuck for hours, i do not understand how i am supposed to use bond energy values for this question like it asks when bond energy values are for molecules in the gas state. The first molecule reactant is a liquid and the second reactant has resonance. I have 0 idea how to approach this. Please help

PF is like the Peanuts strip where Snoopy is waiting to cross the street and the signal turns green, "You have to move your feet." Make some sort of attempt.
