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 statement best explains how enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
Which statement best describes an effect of using a catalyst in an industrial process?
It lowers activation energy requirements.
Which analogy can best be likened to the activation energy of a chemical reaction?
a hill over which the wagon is pushed. - novanet
What best explains the role of a catalyst in a chemical reaction?
The phenomenon which best explains the role of catalyst in a reaction is that the catalyst lowers the Energy of Activation :)
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 is more appropriate description for mitochondria and chloroplasts-energy tranformers or energy producers?
Roque Canillas is the Best!
What is the best description of what happens when a bond is formed?
when a bond forms, energy is released --A+
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.
