Slow reactions have high activation energies
Did you know?
WebbWhen graphically tracking the energy of a reaction, you can see that energy is always needed to start a reaction, regardless of its enthalpy. This necessary energy is called the activation energy. Exothermic reactions, however, have a lower activation energy compared to the reverse endothermic reaction. Webb22 jan. 2024 · In order to understand activation energy, we must first understand what energy is. Energy is the ability to do work. It comes in many forms, such as heat, light, chemical energy, and electrical energy. All of these forms of energy can be converted into each other.The activation energy of a reaction...

WebbFor any reaction to proceed, the starting material must have enough energy to cross over an energy barrier. This energy barrier is known as activation energy (∆G ≠) and the rate of reaction is dependent on the height of this barrier. A low energy barrier corresponds to a fast reaction and high energy barrier corresponds to a slow reaction.
