The total bond energy in the products of the reaction can be calculated by multiplying the number of bonds formed by the bond energy of each bond.
In the reaction, 2 H–Cl bonds are formed, so we multiply the bond energy of H–Cl bond by 2:
2 H–Cl bonds x 427 kJ/mol = 854 kJ/mol
Therefore, the total bond energy in the products of the reaction is 854 kJ/mol.
Use the information in the table to answer the question.
Bond Bond Energy (kJ/mol)
H–Cl 427
Cl–Cl 242
H–H 435
Hydrogen and chlorine gases react to produce hydrochloric acid according to the reaction.
