Does the catalyst change the amount of energy released in the reaction?
no. the amount of catalyst does not influence the reaction; A catalyst simply provides an alternative route for the reaction with a lower activation energy.
The amount of energy released from a fission reaction is much greater than the energy released from a chemical reaction because in a fission reaction?
Thebond energy in an atomic nucleus are greater than the energy of chemical bonds.The binding enegy of a nucleon is 7,6 MeV.
How does activation energy determine if a reaction will release or absorb energy?
Activation energy is really just the minimum amount of energy needed for a chemical reaction to occur. Without it, the energy will stay the same and the substance cannot undergo a chemical change. The thing to look at, I think, is the product of the reaction. For example, in a graph, two substances could have the same activation energy, but after the reaction the amount of energy in substance 1 could be extremely low and the amount of energy in substance 2 could be higher than the activation energy. In substance 1, evidence of an EXOTHERMIC reaction has occurred because the amount of energy in the original substance was lost indicating that it has released energy. Whereas in substance 2, when the amount of energy was higher than the activation energy, it is evident that an ENDOTHERMIC reaction has occurred because the amount of energy after the reaction is higher than it was before the reaction. This shows that substance 2 absorbedenergy making it endothermic. hope this helps!
What does the specific heat of a reaction represent?
This is the quantity of energy needed to maintain all substances involved in a chemical reaction at the same temperature.
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 is energy of reaction?
Energy and Heat of a reaction is the net amount of energy released or absorbed when the reaction is 100% complete
What does the enthalpy of reaction measure?
The amount of energy that is used or released as heat in a reaction.
What does enthalpy of reaction measure?
The amount of energy that is used or released as heat in a reaction.
What does the enthalpy reaction measures?
The amount of energy that is used or released as heat in a reaction.
Does the catalyst change the amount of energy released in the reaction?
no. the amount of catalyst does not influence the reaction; A catalyst simply provides an alternative route for the reaction with a lower activation energy.
What is meant by enthalpy?
amont of energy that can be released - i guess heat
When two nuclei combine in what reaction a huge amount of energy is released?
Fusion
The amount of energy released from a fission reaction is much greater than the energy released from a chemical reaction because in a fission reaction?
Thebond energy in an atomic nucleus are greater than the energy of chemical bonds.The binding enegy of a nucleon is 7,6 MeV.
When a nuclear fission reaction occurs an enormous amount of energy is released This energy comes from?
The release of excess binding energy.
How does activation energy determine if a reaction will release or absorb energy?

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 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.
