Chemists call the energy needed to get a reaction called activation energy. Activation energy was introduced in 1889 by the Swedish scientist Svante Arrhenius.

What energy is needed to start a chemical reaction?
It varies with the differences in chemical reactions
Will an increased temp and an increased concentration speed up a chemical reaction?
Generally, yes. Unless the product of the reaction should be ammonia for example, where a decreased temperature is needed. A catalyst from the transition metals will speed up a reaction too, for example a nickel catalyst in the process of the hydrogenation of margerine as it lowers the activation energy needed for the reaction to start. Increased pressure will also speed up the reaction, no matter what reaction is occurring.
Was the reaction of hydrogen and oxygen endothermic or exothermic How could you tell?
To produce water? Exothermic and very much so.Take a mixture, spark it and it will burn or explode. Heat energy is given off far in excess of whatever energy was needed to start the reaction.
Why does no reaction take place between methane and chlorine at room temperature?
For a reaction between oxygen molecule and hydrogen molecule to take place the bond between the two oxygen atom in O2 and the two hydrogen atom in H2 is required to be breaked. For this process a high temperature is needed which is not possible at room temperature. Since no bond breaks to make an reacting atom, the reaction does not takes place at room temperature
What happens when you mix potassium permanganate with oil?
there will be a chemical reaction called combustion. potassium permanganate as the oxidant and oil obviously as fuel if the two were mixed they needed to release energy in form of heat.
What do chemists call the energy needed to get a reaction started?
The energy needed to start a chemical reaction is called the activation energy :)
The energy that is needed to get a reaction started?
activation energy
What energy is needed to get a reaction started?
Potential energy
What it the term used to describe the energy needed to get a reaction started?
The energy needed to get a reaction started is called activation energy.
Energy needed to get a chemical reaction started?
Activation energy
What is the definition of activation energy?
Energy needed to get a reaction started....
What is the term used to describe energy needed to get a rection started?
ACTIVATION ENERGY IS THE ENERGY WHICH IS REQUIRED FOR INITIALIZING OF ANY TYPE OF REACTION.
What is the amount of energy needed to get a chemical reaction started known as?
activation energy
If an enzyme is present less of what is needed to get the reaction started?
Energy
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
Energy is the energy needed to start a chemical reaction?
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
Which has higer rate of reaction the one with higher temperature or not?
The greater the temperature, the faster the rate of reaction. This is due to the fact that increasing temperature increases the activation energy, which is the amount of energy needed to get a reaction started.
