This energy requirement can be represented graphically as shown below. Why has the reaction shown in the second image not taken place? The activation energy (E A) has not been achieved. Discuss bond ...

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 ...

Activation energy is the minimum energy needed for ‘successful collisions’ where atoms within the reactants rearrange to form products. It can be represented on an energy level diagram.

Again this is an area of skill which may need to be rehearsed but will yeild useful information if pupils are able to manipulate the data competently 1/t or 1/T It is worth noting that we have refered ...

Enzymes lower the activation energy necessary to transform a reactant into a product. On the left is a reaction that is not catalyzed by an enzyme (red), and on the right is one that is (green).
