The value for ΔH° for the reaction below is -72 kJ. How many kJ of heat are released when 1.0 mol of HBr is formed in this reaction?

H2(g) + Br2(l) = 2HBr(g)

1 answer

What about 1/2 that?
The equation tells you that 2 mols HBr were formed with the release of 72 kJ. So 1 mol must release just 1/2 that? right?
