For this problem, we have to calculate the enthalpy of reaction (ΔH) using the given bond enthalpies.
1⁄4 CH4 (g) + Cl2 (g) → 1⁄4 CCl4 (l) + HCl (g)
Recall that the change of enthalpy for a chemical reaction (ΔH) can be calculated using bond energies:
To determine the enthalpy of reaction, we need to first see what bonds are present in the reactants and the products.
Estimate ΔH°rxn for the following reaction, using the chemical reactions given above and the ΔH°rxn values you calculated in part (a). Show all work to support your answer and circle your final answer.
1⁄4 CH4 (g) + Cl2 (g) → 1⁄4 CCl4 (l) + HCl (g) ΔH°rxn = ?
a. +85.8 kJ
