Atomisation Guides d'étude, Notes de cours & Résumés

Detailed notes on Unit 8 - Energetics I covering all the specification points, and allowed me to achieve an A* in chemistry. Covers enthalpy changes, thermochemical equations, Hess's law, Hess cycles, example calculations, standard enthalpy of formation, reaction, combustion, neutralisation and atomisation, bond enthalpy calculations with examples and enthalpy titrations.

Standard enthalpy of formation correct answer: enthalpy change when it is made from the stable form of its elements at standard condition combustion enthalpy correct answer: exothermic, so always negative atomisation enthalpy correct answer: endothermic, so always positive ∆H(rxn)= correct answer: ∑∆Hºf(products) - ∑∆Hºf(reactants) standard enthalpy of formation correct answer: change of enthalpy during the formation of one mole of the substance from its constituent ...

What are standard conditions? 298K/25°C 100kPa/1 atm 1 moldm-3 Enthalpy change of formation The enthalpy change when 1 mole of a compound is formed from its constituent elements under standard conditions, with all reactants and products in their standard states. Enthalpy change of combustion The enthalpy change when 1 mole of a substance is burned completely in oxygen. Enthalpy change of atomisation The enthalpy change that accompanies the formation of 1 mole of gaseous atoms from ...
