Question

Use the molar bond enthalpy data in the table to estimate the value of A Hic for the equation CH,() + 4 CI, (8) --- CCI,(9) +

Please show clear working

Answer 1

Answer #1

Reactant side we have:

4 C-H bonds

4 Cl-Cl bonds

Product side we have:

4 C-Cl bonds

4 H-Cl bonds

Use:

delta H = BE(reactant) - BE(product)

= 4*BE(C-H) + 4*BE(Cl-Cl) - 4*BE(C-Cl) - 4*BE(H-Cl)

= 4*414 + 4*243 - 4*331 - 4*431

= -420 KJ

Answer: -420 KJ
