Is it true or false that all chemical reactions require an initial input of energy called catalysis?
False. Not all chemical reactions require catalysis. Some reactions occur spontaneously, while others may require an initial input of energy in the form of activation energy. Catalysis is a process that lowers the activation energy required for a reaction to occur, but it is not necessary for all reactions.
Why do reactions require activation energy?
Activation energy is needed to overcome the energy barrier and initiate a chemical reaction. It ensures that reactant molecules have enough energy to break existing bonds and form new ones. Without activation energy, reactions would not proceed efficiently or may not occur at all.
Can a reaction have zero activation energy?
No, all reactions require some activation energy to proceed, even if it is very small. Activation energy is the minimum amount of energy required for reactant molecules to transform into product molecules.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
Is Activation energy the minimum energy needed for a reaction to start?
No, the opposite. The lower the activation barrier the faster the reaction goes. That is how a catalyst speeds up the reaction: by lowering the activation energy.See the Web Links for more information.

What would happen if activation energy barriers didn't exist?
Without activation energy barriers, all chemical reactions would proceed instantaneously, as reactions would no longer require energy input to initiate. This could lead to uncontrollable and potentially dangerous reactions in living organisms and the environment. Activation energy barriers act as a protective mechanism to ensure that reactions occur at a controlled rate.
Does all reaction require activation energy?
Yes
Is a catalyst generally required in biochemical reactions?
No, not all biochemical reactions require a catalyst. However, catalysts can help accelerate the rate of biochemical reactions by lowering the activation energy required for the reaction to proceed.
Do all chemical reactions need heat to start them off?
No, not all chemical reactions require heat to start. Some reactions can occur at room temperature or even at low temperatures. Heat is often used to speed up reactions or provide enough energy to overcome the activation energy barrier.
Do all chemical reaction require activation energy?
Yes, they do.
What type of reaction releases energy and does not require initial energy to occur?
All reactions require an activation energy. Some appear not to because that energy is provided enough by their temperature. Thus, there is no reaction that does not require any initial energy to occur. A reaction that results in an overall release of energy is called an exothermic reaction.
What do chemical reactions in living organisms need to start?
Chemical reactions in living organisms require a source of energy to start. This energy is typically obtained from molecules such as ATP. Additionally, enzymes play a critical role in catalyzing these reactions by lowering the activation energy required for the reaction to occur.
Why do all reactions have an activation energy?
Activation energy is the minimum energy required to initiate a chemical reaction by breaking bonds in reactant molecules. It ensures that reactions proceed in a controlled manner, preventing spontaneous and uncontrolled reactions. Activation energy helps regulate reaction rates and allows cells to maintain metabolic processes at appropriate speeds.
Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
