ChemistryEnergy of reactions/Exothermic and endothermic reactionsGCSEOCR Created by: Sophia BoothCreated on: 17-05-18 07:02 Whats the equations for concentration? mass of solute divided by volume of solution. 1 of 5 Equation for concentration in mol/dm^3? Number of moles divided by volume of solution. 2 of 5 What is an exothermic reaction? One which gives out energy to surrondings, usually in the form of heat and usually shown by a rise in temperature of the surrondings. 3 of 5 What is an endothermic reaction? One which takes in energy from the surrondings, usually in the form of heat and usually shown by a fall in temperature of the surrondings. 4 of 5 Whats the activation energy? Minimum amount of energy for bonds to break and a reaction to start. 5 of 5
