How to use in-sentence of “activation energy”:
– The energy difference between “classical” carbocations and “non-classical” isomers is often very small, and there is generally little, if any activation energy involved in the transition between “classical” and “non-classical” structures.
– In the presence of a catalyst the activation energy is reduced.
– The activation energy is the difference in energy between the transition state and the starting reagents.
– Enzymes lower the activation energy of a reaction by forming an intermediary complex with the substrate.
– For example, when you lit the methane gas you are providing the activation energy to burn.
– The activation energy of a chemical reaction is the minimum energy that is needed to make the reaction happen.
