The enthalpy of formation for C6 H6 (I) is 49.0 kJ/mol. Consider the following reaction. 6 upper C (s, graphite) plus 3 upper H subscript 2 (g) right arrow upper C subscript 6 upper H subscript g (l). Is the reaction endothermic or exothermic, and what is the enthalpy of reaction? Use Delta H r x n equals the sum of delta H f of all the products minus the sum of delta H f of all the reactants.. exothermic; Delta.Hrxn = 49.0 kJ exothermic; Delta.Hrxn = –49.0 kJ endothermic; Delta.Hrxn = 49.0 kJ endothermic; Delta.Hrxn = –49.0 kJ
