To determine the total bond energy in the products of the reaction, we need to calculate the bond energy for each bond formed in the product, HCl.
In the reaction, 1 mole of H2 reacts with 1 mole of Cl2 to produce 2 moles of HCl.
The bond energy for the H–Cl bond is given as 427 kJ/mol.
Since 2 moles of HCl are formed in the reaction, the total bond energy in the products is calculated as:
2 moles of HCl * 427 kJ/mol = 854 kJ/mol
Therefore, the correct answer is 854.
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.
H2 + Cl2 → 2HCl
