To calculate the enthalpy change (ΔH) for the reaction: \[ D_2(g) + \frac{1}{2} O_2(g) \rightarrow D_2O(l) \] we will use the bond enthalpies provided for the bonds involved in the reaction. The bond enthalpies are as follows: - D-D bond enthalpy: \( +440 \, \text{kJ/mol} \) - O-O bond enthalpy: \( +498 \, \text{kJ/mol} \) ...
