Chemistry International Baccalaureate (IB) Practice Question: Which equation represents the bond enthalpy for H–Br in hydrogen bromide? a. $HBr (g)→ H^+ (g) + Br^− (g)$ b. $HBr (g)...

$HBr (g)→ H^+ (g) + Br^− (g)$

$HBr (g)→ H (g) + Br (g)$

$HBr (g)→ \frac{1}{2} H_2 (g) + \frac{1}{2} Br_2 (l)$

$HBr (g)→\frac{1}{2} H_2 (g) + \frac{1}{2} Br_2 (g)$
