The sign of change in enthalpy for the vaporization of liquid B r 2 is to be determined. The reaction showing heat as either reactant or product is to be written. Concept Introduction: Enthalpy ( H ) : It is the total amount of heat in a particular system. The value of heat formed in a reaction ΔH is calculated by the formula, ΔH= ∑ ( B o n d D i s s o c i a t i o n E n e r g y ) ( reactants ) − ∑ ( B o n d D i s s o c i a t i o n E n e r g y ) ( products ) If the value obtained for ΔH in a reaction is positive then it is an endothermic reaction whereas the value obtained for ΔH is negative it is an exothermic reaction.
