CH10: Q07 Homework Important Answered What is the AHrxn for the reaction H2 + 12 + 2 HI ? And is the reaction exothermic or e

Explanation :

H2   + I2    ----------->   2 HI

delta Hrxn = deltaHfproducts - deltaHf reactants

                  =2 x 26.5 - 62.4

                  = - 9.4 kJ/mol

delta Hrxn = - 2 kcal /mol
