$\Delta H$

Vedclass · Answer

(A) In an exothermic reaction,heat is released into the surroundings. This implies that the enthalpy of the products $(H_P)$ is less than the enthalpy of the reactants $(H_R)$. Mathematically,the change in enthalpy is given by $\Delta H = H_P - H_R$. Since $H_P < H_R$,the value of $\Delta H$ is always negative for exothermic reactions.
