Question

2Cl2 + O2 → 2Cl2O

How many of each type of bond are present in the reactants?
How many of each type of bond are present in the product?
Use the Bond Energy Table to find the total change in bond energy. (187 kJ/mol)
Is this reaction endothermic or exothermic? How do you know?

Answer 1

endothermic reaction; need more info on the reactants to answer the other questions

Step-by-step explanation:

Given the change in bond energy of 187 kJ/mol, you can determine whether the reaction is endothermic or exothermic. If the bond energy is positive, the reaction is endothermic, meaning it absorbs energy. If the bond energy is negative, the reaction is exothermic, meaning it releases energy. In this case, the bond energy is positive so it's an endothermic reaction.
