Which is the best description of activation energy?
The amount of energy needed to start a chemical reaction. Source: Biology class
Which is a best definition of activation energy?
Activation energy is energy or power conducted that can be instantly activated for use when flick a light switch you used activation energy.
Which is more appropriate description for mitochondria and chloroplasts-energy tranformers or energy producers?
Roque Canillas is the Best!
How can activation energy be reduced?
Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of reaction.
Which analogy can best be likened to the activation energy of a chemical reaction?
The activation energy of a chemical reaction can be likened to pushing a car up a hill before it can roll down to the other side. Just like how the initial push is needed to start the motion, the activation energy is required to initiate a chemical reaction. Once the reaction is started, it can proceed spontaneously.
What best explains the role of a catalyst in a chemical reaction?
A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does this by providing an alternative reaction pathway with a lower energy barrier. The catalyst itself is not consumed in the reaction and can be reused multiple times.
How could you make sure that more particles have the activation energy in a chemical reaction?
The easiest way to overcome most activation energies is to heat the reaction. And the best way to make sure heat is evenly distributed so that more particles can use this energy is to stir the reaction mixture.
After sunlight hits photosystem 2 what is the best description of what happens?
solar energy changes adp into atp.
Which statement best explains how enzymes speed up chemical reactions?
Enzymes speed up chemical reactions by lowering the activation energy needed for the reaction to occur. This allows the reaction to happen more quickly, as enzymes provide an alternative pathway with a lower energy barrier for the reaction to proceed. Ultimately, enzymes help substrates to reach the transition state more easily, facilitating the reaction.
What is the best description for tissue?
The best description for tissue is to blow your nose
Which is the best description of bronchioles?
description of the bronchioles
According to collision theory what best explains how a catalyst increases the reaction rate for a chemical reaction?
A catalyst decreases the threshold energy for a chemical reaction. A catalyst decreases energy required for two particles to react. A catalyst lowers the amount of energy needed to reach the transition state.
