What is the best definition of activation energy?
The best definition of activation energy is that activation energy is the energy required to bind a substrate to an active site (option C).
Which definition best describes the term activation energy quizlet?
Which is the best definition of activation energy? the energy required to form or break the bonds of reactant molecules.
What is activation energy in biology?
activation energy: The minimum energy required for a reaction to occur. catalysis: The increase in the rate of a chemical reaction by lowering its activation energy.
What is the best example of activation energy?
This energy is called activation energy. For example, activation energy is needed to start a car engine. Turning the key causes a spark that activates the burning of gasoline in the engine. The combustion of gas won't occur without the spark of energy to begin the reaction.
What is energy of activation quizlet?
Activation energy is the energy required to break existing bonds, and form new bonds. If a collision occurs with more energy than the activation energy, the reaction will occur. Rate of reaction is determined by the number of collisions that occur, and how effective they are.
What exactly is the activation energy of a chemical reaction doing quizlet?
Activation energy is the energy absorbed before it can start a chemical reaction.
Which description explains the role of activation energy in a chemical reaction?
Which description explains the role of activation energy in a chemical reaction? It provides useful energy that is released in an exothermic reaction.
Is activation energy exothermic?
Explanation: When graphically tracking the energy of a reaction, you can see that energy is always needed to start a reaction, regardless of its enthalpy. This necessary energy is called the activation energy. Exothermic reactions, however, have a lower activation energy compared to the reverse endothermic reaction.
What causes activation energy?
The source of activation energy is typically heat, with reactant molecules absorbing thermal energy from their surroundings.
