Why are fractional coefficients permitted in a balanced thermochemical equation? Fractional coefficients are permitted in order to have the smallest possible set of coefficients for a given reaction. Fractional coefficients are permitted because the enthalpy change for the reaction is dependent on the amount of matter present. Fractional coefficients are permitted because the enthalpy change for the reaction is independent of the amount of matter present. In thermochemical reactions, only small amounts of matter are considered. O If fractional coefficients were not used, the scale of the reaction would be excessively large.
