The energy necessary to start a chemical reaction?
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
The amount of energy needed to cause a chemical reaction to occur is the?
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
What must be absorb before a chemical reaction can start by the reactants?
energy
A chemical reaction that releases energy is called?
Exothermic reactions
Chemical reaction that releases energy?
All chemical reactions that release energy in the form of heat are called exothermic reactions.
What chemical reaction produces heat and energy in a star?
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.
What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
What type of chemical absorbs energy?
The two kinds of chemical reactions are endothermic and exothermic. A chemical reaction that absorbs energy is called an endothermic reaction.
What is the relationship between the temperature and the rate of chemical?
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
The activation energy of a reaction refers to the minimum amount of energy?
required for the reaction to occur. It is the energy barrier that must be overcome for the reactants to transform into products. Increasing the temperature can help molecules acquire the necessary energy to reach the activation energy.
When energy is absorbed in a chemical reaction its called?
endothermic
