WebHess' Law for bond enthalpies is: ΔH = Σ E reactant bonds broken − Σ E product bonds broken. −108 = [239 + 159] − 2x. −2x = −506. x = 253 kJ/mol. Note the use of 2x because there are two ClF molecules. Example #5: The reaction of H 2 with F 2 produces HF with ΔH = −269 kJ/mol of HF. WebJul 6, 2024 · Photocatalytic conversion of lignocellulose to valuable aromatics has significant potential for applications in biorefineries.
