Question

The total bonding energy for the products of a reaction is 2535 kJ/mol and the bonding energy of the reactants is 1375 kJ/mol. Calculate the change in enthalpy, and classify the reaction as endothermic or exothermic.
-1160 kJ/mol, endothermic
1160 kJ/mol, exothermic
-1160 kJ/mol, exothermic
1160 kJ/mol, endothermic

Answer 1

Answer:

-1160kj/mol

Explanation:

the reaction is exothermic because heat is released to the environment
