Question

The following energy diagram depicts the energy changes involved for A+B AB

(a) Is the following diagram an exothermic or endothermic reaction?

(b) Explain how you arrived at this conclusion.

Answer 1

Hi Camila,

I don't see an energy diagram in the post, but you can always tell if an energy diagram is endothermic if the products are at a higher level than the reactants (energy absorbed). It is exothermic if the products are lower than the reactants (energy was lost). Hope this helps!
