________________
hydrogen and chlorine gases react to produce hydrochloric acid according to the reaction
H2 + CI2 > 2HCI
how much total bond energy, in kJ/mol, is in the products of the reaction?
A ) 435
B ) 854
C ) 677
D ) 427
To find the total bond energy in the products of the reaction, we need to look at the bond energies provided for the products.
The reaction is:
H₂ + Cl₂ → 2HCl
For each molecule of HCl formed, there is one H-Cl bond. Since the reaction produces 2 moles of HCl, we will have 2 moles of H-Cl bonds.
The bond energy for an H-Cl bond is given as 427 kJ/mol.
Since we have 2 moles of HCl, we need to multiply the bond energy of one H-Cl bond by 2:
Total bond energy in the products = 2 × (bond energy of H-Cl)
Total bond energy in the products = 2 × 427 kJ/mol
Total bond energy in the products = 854 kJ/mol
Therefore, the total bond energy in the products of the reaction is 854 kJ/mol.
The answer is B) 854.
