What is the H of the reaction The average bond energies of C - Cl bond and C - H bond are 416 kJ and 325 ~kJ ~mol ⁻¹ respectively.

Options

  1. A1482 kJ
  2. B1482 J
  3. C1492 kJ
  4. D1492 J

Correct answer

A. 1482 kJ

Step-by-step solution

In the reaction, two moles of C - H bonds and two moles of C - Cl bonds are broken. Hence, energy absorbed aligned & =2 416+2 325 & =1482 ~kJ aligned
