Given that C_ (g) + 4H_ (g) CH_ 4(g) H^0 = -1665 kJ What is bond energy per mole of C-H bond?

MHT CET 2024 Chemistry question

Given that kJ What is bond energy per mole of C-H bond?

(A)416 kJ molCorrect
(B)-416 kJ mol
(C)832.5 kJ mol
(D)-832.5 kJ mol

Answer: (A)

Solution

The reaction forms four C-H bonds from gaseous atoms, so the enthalpy released ( kJ) is the sum of the bond-formation enthalpies of four C-H bonds. Bond energy (bond dissociation enthalpy) is the energy required to break the bond and is
