endothermic reaction
The activation energy refers to a chemical reaction.
Technically, it isn't "heat" that makes a chemical reaction happen. "Heat" is merely the flow of energy from one place to another. It is the energy itself that causes a reaction to occur. As an increase in temperature occurs, there is an increase in the energy in a group of molecules by making them mover around faster and bum into each other more. This energy is called "Activation energy", and is defined as the amount of energy required to make the reaction start and carry on spontaneously. Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy. With that being said, activation energy is the answer
A catalyst speeds up a reaction rate because it lowers the activation energy. The activation energy is the amount of energy required to start a reaction. If less energy is needed, then the same amount of energy can react more times.

In chemistry, activation energy is a term introduced in 1889 by the Swedish scientist Svante Arrhenius that means the minimum energy that must be input to a chemical system with potential reactants to cause a chemical reaction. Activation energy may also be defined as the minimum energy required to start a chemical reaction.The activation energy of a reaction is usually denoted by Ea and given in units of kilojoules per mole

The activation energy refers to a chemical reaction.
Enzymes speed up a reaction by lowering the activation energy. This is the amount of energy required to start the reaction. By lowering the activation energy, the reaction can proceed much more quickly.

No, the opposite. The lower the activation barrier the faster the reaction goes. That is how a catalyst speeds up the reaction: by lowering the activation energy.See the Web Links for more information.
A catalyst speeds up a reaction rate because it lowers the activation energy. The activation energy is the amount of energy required to start a reaction. If less energy is needed, then the same amount of energy can react more times.
Energy required for a reaction can vary. Depending on the atom it changes. The element will be more reactive if it has a low 1st ionization energy since it requires less energy to react. The most reactive element in Francium since it has the lowest 1st ionization energy level. If an element has a high electro-negativity then it will also be able to react with little energy.
The chemical term activation energy is the amount of energy required for a chemical reaction to take place. For more information about different chemical contact a scientists or science professor in one's area.
Catalysts actually lower the activation energy needed to start a chemical reaction. This makes the reaction happen more easily.
lower activation energy, make the reaction more economical
A chemical catalyst is a substance that lowers the required activation energy of a reaction. The activation energy is the amount of energy required to "activate" or start a process, this can be in the form of many things, such as heat. A chemical catalyst can be seen as a kind of shortcut in a chemical process to speed things up. A catalyst can also be used to increase the activation energy, so that the reaction will slow down. This is useful for slowing down reactions that are normally too fast to witness.
