True:
ΔH = H((final) - H(initial). But in an exothermic reaction:
H(final) < H(initial), so:
ΔH < 0

The enthalpy (warmth) for an exothermic reaction must be damaging using fact extra potential is released whilst the products are shaped than is used whilst the reactants are broken up.

in an exothermic reaction the system loses energy as heat is released.hence the enthalpy change is negative
and in an endothermic reaction heat is absorbed ie the energy of the system surges.hence delta H is +ve
but in physics the concept is opposite.
