You can find all my A Level Chemistry videos fully indexed at https://www.freesciencelessons.co.uk/... • In this video, we start looking at the topic of enthalpy. First I explain to you why we tend to measure enthalpy change rather than enthalpy itself. I then take you through how to draw an enthalpy profile diagram for an exothermic reaction and what is meant by activation energy. I finish by showing you how to draw an enthalpy profile diagram for an endothermic reaction. • This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification. • Image Credits: • Thermite reaction • https://commons.wikimedia.org/wiki/Fi... • User:Nikthestunned (Wikipedia), CC BY-SA 3.0 (https://creativecommons.org/licenses/..., via Wikimedia Commons
