Activation energy in chemistry is the amount of energy required to start a reaction. For every chemical reaction, a certain amount of energy is required to start it. The diagram represents how much energy it takes to do this, and also shows how much energy you get from it.
With this diagram, you can also calculate the energy of products, reactants, e.t.c.
This is also a useful diagram to explain the function of a catalyst, something used to decrease the activation energy.

What is the minimum amount of energy needed to start a chemical reaction?
activation energy ( I know it is right because it is in my science book)
Which of the following conclusions can be drawn from the curves in the energy diagram?
. The reaction represented by curve B will go faster than the curve A reaction.
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What term is used to describe the minimum amount of energy required in order for a reaction to proceed?
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
How does energy involved chemistry?
For example any chemical reaction need an activation energy.
What represents the highest energy point on an energy diagram?
activation energy
What effect does an enzyme have on a activation energy needed to start a reaction?
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
What is activation energy and how do enzymes effect it?
There is no straight forward relation between enzyme and activation energy because although energy of reaction is fixed and is governed by laws of chemistry but for biochemical reactions concentration of enzyme and conc. of substrate affect rate of reaction and energy, but in general enzymes decrease activation energy of reaction.
How does an enzyme catalyze a chemical reaction in regards to activation energy?
Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.
What is the role of activation energy in inorganic chemistry?
Activation energy is needed to trigger some non-organic chemical reactions, For example the use of a blasting cap to detonate high explosives.
What is the activation energy for crystal violet and NaOH?
We just did this for our chemistry final. We did it completely wrong...But our teacher told us that the actual activation energy is somewhere between 20 and 30 kcals. Hope this helps!
What is the minimum amount of energy needed to start a chemical reaction?
activation energy ( I know it is right because it is in my science book)
What is activators used for?
Activation energy in chemistry is the amount of energy required to start a reaction. For every chemical reaction, a certain amount of energy is required to start it
Reactants and products in an energy diagram?
Activation energy is the distance from the reactants to the top of the "hill."
Which of the following conclusions can be drawn from the curves in the energy diagram?
. The reaction represented by curve B will go faster than the curve A reaction.
What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
