Question

The bond dissociation energy of H-Br is 362 kJ/mol. Which one of the following proceses will release 362kJ of energy?

A. H(g) + Br(g) -> HBr(g)
B. HBr (g) --> H(g) + Br (g)
C. 1/2 H2 (g) + 1/2 Br2 (g) -> HBr (g)
D. HBr (g) --> 1/2 H2 (g) + 1/2 Br2 (g)

Answer 1

building requires energy while breaking down releases.

Answer 2

thanks for the hint :-)
