A reaction profile includes the activation energy, which is the minimum energy needed by particles when they collide for a reaction to occur. The activation energy is shown as a 'hump' in the line ...

Do not attempt to perform this demonstration. The combustion of methane is an example of an exothermic reaction. More energy is released when the bonds in the products are formed than is used to break ...

Temperature, concentration, pressure and the use of catalysts affect reaction rate. Heat energy changes in chemical reactions - Edexcel Exothermic reactions in solution give out energy and the ...

If this chain reaction went too fast, it became an atomic explosion, but under control it could produce a steady flow of energy. (If the chain reaction started with uranium, it also created a ...
