What else can I help you with?
What decreases activation energy needed for a chemical reaction?
The presence of a catalyst in a reaction will lower the activation energy required to complete the reaction. The catalyst is not used up in the reaction, it is just there to speed it up.
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.
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
Is more energy required for a chemical reaction in the absence of an enzyme?
Without an enzyme, the activation energy needed to start a reaction is much greater. An enzyme is a catalyst, which decreases the amount of activation energy needed to start a reaction. By doing so, it decreases the amount of time the chemical reaction takes place.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What energy is the energy needed to start a reaction?
Activation Energy.
The energy that is needed to get a reaction started?
activation energy
What activation energy is needed for a chemical reaction is decreased by?
The activation energy is decreased by a catalyst.
A reaction in which it seems no activation energy is needed?
a spontaneous reaction
What effect does an enzyme have on a activation energy needed to start a reaction?
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
What is the minimum amount of energy needed to start a chemical reaction?
The minimum amount of energy needed to start a chemical reaction is called the activation energy. It is the energy required to break the bonds in reactant molecules and initiate the reaction. Once this energy barrier is overcome, the reaction proceeds without additional energy input.
Energy needed to get a chemical reaction started?
Activation energy
