Solution: Enter your answer in the provided box.You are given the following data: H2 (g) → 2H (g) ΔH° = -436.4 kJ/mol Br2 (g) → 2HBr (g) ΔH° = 192.5 kJ/mol H2 (g) + Br2 (g) → 2HBr (g) ΔH° = -72.4 kJ/mol Calcula

Enter your answer in the provided box.

You are given the following data: 

H₂ (g) → 2H (g) ΔH° = -436.4 kJ/mol 

Br₂ (g) → 2HBr (g) ΔH° = 192.5 kJ/mol 

H₂ (g) + Br₂ (g) → 2HBr (g) ΔH° = -72.4 kJ/mol 

Calculate ΔH° for the reaction 

H (g) + Br (g) → HBr (g)
