Chemistry Coursework : Neutralisation Prediction: I predict that the reaction will be endothermic. If we increase the concentration of acid, the temperature change will increase. Background information: Reactions: An EXOTHERMIC REACTION is one which usually one which gives out energy to the surroundungs, usuually in the form of heat and usually shown by a rise in temperature. An ENDOTHERMIC REACTION is one which takes in energy from the surroundings, usually in the form of heat and usually shown by a fall in temperature. Energy level diagram: Energy transfer: A reaction that gives out energy is called n exothermic reaction. A reaction that takes in energy is alled an endothermic reaction. Exothermic reactions can feel hot as energy is taken in. Endothermic reactions can feel cold as energy is taken in. The energy change in a reaction is often given the symbol /\H. For endothermic reactions the energy change is positive , i.e heat is needed....
