Why do biological reactions have a high activation energy and Why?
Biological reactions often have a high activation energy because they involve complex molecules and reactions that require a significant input of energy to overcome the initial energy barrier. This high activation energy helps regulate the rate of biological reactions and ensures that they proceed only when necessary for the cell or organism.
What is the role of activation energy in inorganic chemistry?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. In inorganic chemistry, activation energy determines the rate at which reactions proceed. Higher activation energy results in slower reactions, while lower activation energy results in faster reactions. By understanding activation energy, chemists can optimize reaction conditions and develop more efficient processes.
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
The activation energy for the chemical reaction in living thing is high or low?
The activation energy for chemical reactions in living things is typically low compared to non-biological reactions. This is because living organisms rely on enzymes to catalyze reactions, lowering the energy barrier needed for the reaction to occur. This allows for faster and more efficient processing of biological molecules.
Catalysts speed up chemical reactions by?
Catalysts are very effective and economical in industrial area. Catalysts increase the rate of a reaction by reducing the activation energy of the reaction. activation energy is the overall energy needed for a reaction to initiate. Both reactions such as exothermic or endothermic has activation energy, so we need to overcome the activation energy for the reaction to proceed. Actually the way it works is quiet simple, it absorbs the reactant particles on its surface reducing their bond energy. When the energy between bonds is weaker, its easier for reactant particle to change to products. Activation energy comes from when reactant particles collide with each other with high kinetic energy.
How is activation energy related to bond energy?
Activation energy is the minimum energy required for a chemical reaction to occur. It is related to bond energy because breaking chemical bonds and forming new bonds requires energy, which contributes to the activation energy of a reaction. Bonds with higher bond energy are more stable and require more energy to break, hence increasing the activation energy of the reaction.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.
Does endothermic have a high or low activation energy?

Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

Activation energy to break chemical bonds is provided by what?
"Activation energy to break chemical bonds is provided by what" Answer: High speed collisions between reactant atoms.

Higher activation energy results in slower reactions, while lower activation energy results in faster reactions. By understanding activation energy, chemists can optimize reaction conditions and develop more efficient processes.
What conditions would likely cause the activation energy to be high?
the temperature is hot
What are slowed reactions?
Chemical reactions that have high activation energy, with multiple intermediates and transitions states that have higher activation energy than the initial requirement, but which still have a negative Gibbs free energy change.
Energy of activation is?
The energy need to activate something depends on what is being activated. These energies can range from high to low.
Which of the following combinations will generally produce the slowest reaction?
The combination of a low temperature and a high activation energy will generally produce the slowest reaction. A low temperature slows down the kinetic energy of the reacting molecules, while a high activation energy requires more energy for the reaction to occur.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
The activation energy of an endothermic reaction is at least as large as its enthalpy change because the reactants require a minimum amount of energy to reach the transition state where bond-breaking and bond-forming occur. The enthalpy change represents the overall energy difference between reactants and products but does not account for the energy needed to overcome the energy barrier (activation energy) for the reaction to proceed.
Activation energy barriers?
The activation energy is the amount of energy needed to start a reaction. If the reactants have less than that amount the reaction will not occur. In this way it acts as a barrier that prevents a reaction unless there is enough energy to break it.
