We expect the enthalpy of cumbustion of two isomers to be the molecular formulas of two molecules are so the balanced chemical equation for the two combustion reactions in calculation of combustion enthalpy from of products and reactants, the difference will be in the the
different, isomers, standard enthalpies of formation, combustion products, standard enthalpies of combustion, the same, very similar
the rod-shaped n-pentane has than the neopentane
tetrahedral, less, vibrational and rotational motions, more, translational motion, spherical
