# Problem: If the internal energy of the products of a reaction is higher than the internal energy of the reactants, what is the sign of ΔE for the reaction?

###### FREE Expert Solution

Recall that ΔE is the difference in internal energy between the products and the reactants:

$\overline{){\mathbf{∆}}{\mathbf{E}}{\mathbf{=}}{{\mathbf{E}}}_{{\mathbf{products}}}{\mathbf{-}}{{\mathbf{E}}}_{{\mathbf{reactants}}}}$
