Calculate the enthalpy change of the reaction,
$\text{H}_2\text{(g)} + \text{Cl}_2\text{(g)} \rightarrow 2\text{HCl(g)}$
if bond energies (kJ mol$^{-1}$):
H–H = 436, Cl–Cl = 242, H–Cl = 431
$\text{H}_2\text{(g)} + \text{Cl}_2\text{(g)} \rightarrow 2\text{HCl(g)}$
if bond energies (kJ mol$^{-1}$):
H–H = 436, Cl–Cl = 242, H–Cl = 431
