Best answer


Activation energy is defined as theminimum amount of extra energy required by a reacting molecule to get converted into product. It can also be described as the minimum amount of energy needed to activate or energize molecules or atoms so that they can undergo a chemical reaction or transformation.

  • What is activation energy in chemistry?

  • Written By: Activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.

  • What is the activation energy problem?

  • Activation Energy Problem. Solution Activation energy is the amount of energy required to initiate a chemical reaction. If less energy is available, a chemical reaction is unable to proceed. The activation energy can be determined by reaction rate constants at different temperatures by the equation ln (k 2 /k 1) = E a /R x (1/T 1 – 1/T 2)…

  • What is the relationship between activation energy and rate constant?

  • The more activation energy that is required to reach the transition state, the longer it takes to create a chemical reaction. Because the reaction time is longer, the rate constant is lower. Therefore, the lower an activation energy is to reach the transition state, the higher the rate constant will be.

  • How does the presence of enzymes affect the activation energy?

  • That is, if the activation energy is lowered by the presence of an enzyme, the number or reaction events per second will increase, making the whole reaction happen faster. The activation energy is the energy required to start a reaction.
