What is the total amount of energy needed to break the Cl-Cl bonds in 4 molecules of the reactant Cl2?
1,724 kJ/mol
b.
3,036 kJ/mol
c.
- 412 kJ/mol
d.Endothermic
e.
1,656 kJ/mol
f.
968 kJ/mol
g.Exothermic
h.
2,624 kJ/mol
i.
1,312 KJ/mol
The total amount of energy needed to break the Cl-Cl bonds in 4 molecules of Cl2 can be calculated by multiplying the energy required to break one Cl-Cl bond by the number of Cl-Cl bonds present in 4 molecules of Cl2.
The energy required to break one Cl-Cl bond is given as 1,724 kJ/mol.
There are 2 Cl-Cl bonds in one molecule of Cl2, so in 4 molecules of Cl2, there would be a total of 8 Cl-Cl bonds.
Therefore, the total energy needed to break the Cl-Cl bonds in 4 molecules of Cl2 is:
1,724 kJ/mol * 8 = 13,792 kJ/mol.
Since none of the given options match this value, none of the provided answers are correct.
