ALEVEL CHEMISTRY - Enthalpy Changes Notes and Definitions

Calculate the enthalpy change for the reaction: C(graph) + 2H2(g) + 1/2O2(g) CH3OH(l) Using the following information: C(graph) + O2 CO2(g) ΔHof = ─393.5 kJ. H2(g) + 1/2O2 H2O(l) ΔHof = ─285.8 kJ. CH3OH(l) + 3/2O2(g) CO2(g) + 2H2O(l) ΔHorxn = ─726.4 kJ A. ─1691.5 kJ B. ─238.7 kJ C. 1691.5 kJ D. 47.1 kJ E. ─47.1 kJ - ANSWER B

The PDF provides an in-depth explanation of enthalpy change (ΔH), focusing on how energy changes during chemical reactions. It differentiates between exothermic (energy-releasing) and endothermic (energy-absorbing) reactions, with diagrams illustrating the energy pathways. Key concepts like standard enthalpy changes and reaction pathway diagrams are discussed. It also explains how bond energies affect reactions, with detailed examples showing how to calculate enthalpy changes using bond energie...
