The energy needed for a chemical reaction, known as activation energy, can be decreased by the presence of a catalyst. Catalysts work by providing an alternative reaction pathway with a lower activation energy, thereby increasing the reaction rate without being consumed in the process. Additionally, factors such as increasing temperature or concentration can also decrease the effective activation energy needed for a reaction to occur.

What is the activation energy needed for a chemical reaction decreased by?
The activation energy is decreased by a catalyst.
The energy released when a chemical compound reacts to produce new compounds?
This is known as the heat of reaction, which represents the energy change that occurs during a chemical reaction. It can be exothermic (energy is released) or endothermic (energy is absorbed). Heat of reaction is typically measured in kilojoules per mole of the reactants.
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.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
What is the name of a chemical reaction that gives out energy?
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
What activation energy is needed for a chemical reaction is decreased by?
The activation energy is decreased by a catalyst.
What is the activation energy needed for a chemical reaction decreased by?
The activation energy is decreased by a catalyst.
What is the definition for chemical energy?
Chemical energy is the potential energy stored in the chemical bonds of a substance. This energy is released when these bonds are broken during a chemical reaction, resulting in the conversion of chemical energy into other forms of energy such as heat, light, or kinetic energy.
What is the definition chemical energy?
Chemical energy is a form of potential energy stored within the chemical bonds of a substance. When chemical reactions occur, this energy can be released in the form of heat or light. It is a type of energy that is associated with the breaking and forming of chemical bonds.
The energy released when a chemical compound reacts to produce new compounds?
This is known as the heat of reaction, which represents the energy change that occurs during a chemical reaction. It can be exothermic (energy is released) or endothermic (energy is absorbed). Heat of reaction is typically measured in kilojoules per mole of the reactants.
Why activation energy is referred in the definition of enzymes?
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.
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.
What is the best definition of the enthalpy of a reaction?
The enthalpy of a reaction is the heat change that occurs during a chemical reaction at constant pressure. It represents the difference in energy between the products and reactants in the reaction.
Definition of chemical energy?
Chemical energy is a form of potential energy stored in the bonds of chemical compounds. It is released when a chemical reaction takes place, resulting in the transformation of chemical substances into different forms. This energy can be harnessed and converted into other forms of energy for various applications.
What is the definition of activation energy?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. It represents the energy barrier that must be overcome for reactant molecules to transform into products. Higher activation energy results in slower reaction rates.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
What is the definition of 'exothermic'?
Exothermic refers to a chemical reaction or process that releases energy in the form of heat. This means that during an exothermic reaction, energy is being transferred from the system to the surroundings, resulting in a temperature increase.
