All combustion reactions are exothermic.
Enthalpies of products are greater than enthalpies of reactants `(Sigmav_(p)Delta_(f)H(P)gtSigmav_(R)Delta_(f)H(R))`

Statement-1: All combustion reactions are exothermic. Statement-2: Enthalpies of products greater than enthalpies of reactants (Sv_(p)D_(f)H(P) gt Sv_(R)D_(f)(R))

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement-I : All combustion reactions are exothermic. Statement-II : Enthalpies of products are greater than enthalpies of reactants (sumV_PDelta_fH(P) gt sum V_RDelta_f H(R))
