What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What happens to the potential energy of the molecules in a reaction?
The potential energy of the molecules change during 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).
A chemical reaction that releases energy is called?
Exothermic reactions
What is the amount of energy a reaction needs to take place?
The amount of energy a reaction needs to take place is called activation energy. When this much energy is present, a chemical reaction can occur.
A reaction that gives out energy?
... is an exothermic reaction (opposite of 'endothermic')
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.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What is the reaction in which energy is released?
A reaction that releases energy is usually termed exothermic reaction. Energy is usually released as heat.
What is a chemical reaction in which energy is absobed?
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
What is a reaction that releases energy into its surroundings?
An exothermic reaction releases energy to its surroundings.
What happens to the potential energy of the molecules in a reaction?
The potential energy of the molecules change during a reaction.
What is the differences between exothermic reaction and endergonic reaction?
exothermic reaction releases energy and endergonic reaction absorbs energy
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).
A chemical reaction that transfers energy from the reactants to the surroundings is reffered to as?
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
What is the difference an exothermic reaction and an endothermic reaction?
Exothermic (hyperthermic) reaction: a chemical reaction that releases energy,*Endothermic (hypothermic) reaction: a chemical reaction that absorbs energy.** Energy = heat, light, etc.The direction of Heat transfer:Exothermic reactions transfer heat energy to the environment.Endothermic reactions transfer heat energy from the environment .
