Endothermic and Exothermic Reactions Revision cards on endothermic and exothermic reactions :) 0.0 / 5 ? ChemistryEnergy of reactions/Exothermic and endothermic reactionsGCSEAQA Created by: neve_xxCreated on: 30-09-22 17:09 Endothermic - Definition Endothermic means.... A reaction that takes in thermal energy from the surroundings Which sounds complicated but here's the easier to understand definition: A reaction that gives in heat (like the sun) from what's around them 1 of 11 Exothermic - Definition Exothermic is the complete opposite of endothermic but it is weirdly similar.... Exothermic means: a reaction that releases thermal energy to the surroundings Easy def. = A reaction that releases heat to what's around them Example = burning of candles 2 of 11 Graph Question What type of reaction is shown in the reaction profile above? An exothermic reaction An endothermic reaction ANSWERS ON THE NEXT CARD!!!! 3 of 11 Answers!!!! Answer: Endothermic it is an endothermic reaction because the products have more energy than the reactants, so they must have taken in energy from the surroundings 4 of 11 Graph Question #2 A B C Answer on next card! 5 of 11 Answer!!! Answer: A The energy change of the reaction is the difference in energy between the reactants and the products 6 of 11 Fill in the Gaps react / energy / minimum / maximum Activation energy is the amount of the reactant particles require in order to collide with each other and . 7 of 11 Answer! 1. minimum 2. energy 3. react 8 of 11 Question If an endothermic reaction occurs in a closed container, what would happen to the temperature inside the container? The temperature would increase The temperature would decrease 9 of 11 Answer!
