Which molecules lower the activation energy?
Enzymes lower the activation energy of reactions.The activation energy of a reaction is the amount of energy that has to be put into the system before the reaction proceeds of its own accord. It is like setting fire to a log. First you must supply enough energy by burning a match, paper, kindling, and so on, until the log is hot enough to catch and continue burning on its own. This energy that you supply is the activation energy.When an enzyme is present, the activation energy is lower, and so the reaction proceeds more readily at the temperature of the organism. A concept known as the induced-fit modelexplains how enzymes lower activation energy, by suggesting that the interaction of a substrate with an active site on the surface of the enzyme causes a change in the enzyme's shape, which in turn affects the substrate in such a way as to encourage the reaction.
What Activation energy play in a chemical reaction?
Activation energy tells you how much energy chemical reaction needs to start. Example paper wont suddenly start burning, but you need first to put some energy in paper, before that reaction starts.
Since paper is supposed to burn when it come into contact with oxygen then why doesn't this always happen?
Neither of the reactants have enough energy to overcome the activation barrier at room temperature - paper isn't supposed to just burn on contact with oxygen.
Is the burning of paper a spontaneous reaction?
If you hold a match to the paper, then yes, the reaction is spontaneous.
What are the parts of a match stick?
A match contain a stick (from wood or paper) and a head with the active components.
What is an example activation energy?
holding a lit match to paper
What is an example of how to supply activation energy to begin a reaction?
Activation energy is the minimum amount of energy needed for the reactants to get converted to products. It can be supplied as heat energy, electrical energy, mechanical energy, and light energy.

What does activation energy have to do with temperature?
In most cases, it is thermal energy which activates chemical reactions. In the most easily observed example, we ignite a flammable substance by heating it to its ignition temperature (in the case of paper, 451oF). The hotter something is, the more thermal energy is available to activate a reaction.
Where can you find an activation code for mall tycoon 3?
inside the game case its on a paper inside the game case its on a paper inside the game case its on a paper

How does paper towels hold soda?
by holding it
Why must the paper touch the flame to burn a piece of paper?
The products contain more energy than the reactants.
Is the burning of paper a spontaneous reaction?
If you hold a match to the paper, then yes, the reaction is spontaneous.
Why is paper clip necessary?
a paper clip is not neccessary but is an easy way of holding paper and other materials together
