activation energy

I would also like to know how activation energy works.

Where does the activation energy come from to start the reaction?

You'd have to give it some activation energy before the heat is released.

I always get this mixed up, that means the activation energy is high right?

This material is not stable because of its low activation energy.

The concept of an activation energy should not be taken too literally.

Your question about "activation energy" is specific enough to give a partial answer.

It is also the step that must be used to calculate the activation energy.

When using a catalyst the activation energy is made smaller.

The reaction with the lower activation energy will proceed at a greater rate.

It works instead by lowering the required activation energy for the reaction to take place.

For a chemical reaction to occur, an activation energy must be added.

This equation is a way of calculating the activation energy.

The graph below shows the catalyst's effect on the activation energy.

This is the most difficult step in the mechanism to go through, because it has the highest activation energy.

The reaction is exothermic but has a high activation energy.

However, an activation energy is required - the match has to be struck first, before the reaction can take place.

In the presence of a catalyst (red line) the activation energy is reduced.

Diamond would have a higher activation energy than those, needing heating even more.

The rate, however, becomes more complicated to calculate, because you need to also take the new activation energy into account.

The activation energy of this reaction from these data is then:

There also exist cases where the ignition factor is not the activation energy.

It's not yet clear what the activation energy represents, says Gillooly.

An energy barrier is the same thing as a positive activation energy.

I distinctly remember we were learning about chemical changes and activation energies.
