What is the relationship between the activation energy, activated complex, and reaction rate as depicted on a graph?
On a graph, the activation energy represents the minimum energy required for a reaction to occur. The activated complex is the unstable intermediate state during a reaction. The reaction rate is influenced by the activation energy and the stability of the activated complex. A lower activation energy and a more stable activated complex typically result in a higher reaction rate.

What is the relationship between the rate constant of a reaction and the activation energy of the reaction?
The rate constant of a reaction is directly related to the activation energy of the reaction. A higher activation energy typically results in a lower rate constant, meaning the reaction proceeds more slowly. Conversely, a lower activation energy usually leads to a higher rate constant, indicating a faster reaction.
What is the relationship between temperature and the activation energy required for a chemical reaction, as shown in a graph?
As temperature increases, the activation energy required for a chemical reaction decreases. This relationship is typically shown on a graph where the activation energy is plotted on the y-axis and temperature is plotted on the x-axis.
What is the relationship between an energy diagram and activation energy in a chemical reaction?
An energy diagram shows the energy changes that occur during a chemical reaction. Activation energy is the minimum amount of energy required for a reaction to occur. In the energy diagram, the activation energy is the energy barrier that must be overcome for the reaction to proceed. A higher activation energy means a slower reaction, while a lower activation energy means a faster reaction.
What is activation barrier?
The question is this "what is an energy barrier?" My answer: First of all, activation energy is energy that is needed to start a reaction and barrier means to block so then energy barrier means to block energy.
What is the relationship between the concentration of reactants and the rate of a second-order reaction as depicted on a graph?
In a second-order reaction, the rate of the reaction is directly proportional to the square of the concentration of the reactants. This relationship is depicted on a graph as a straight line with a positive slope, showing that as the concentration of the reactants increases, the rate of the reaction also increases.
When the catalyst bonds with the activated complex what is its effect on the activation energy and the rate and nbsp?
The activation energy is lower and the reaction rate increase.

What part does Activation Energy play on the catalyst cycle?
This obeys to the theory of absolute reaction rates or transition state theory, developed by Henry Eyring in the 1930s. This is a theory of chemical kinetics according to which the velocity of a chemical reaction is proportional to the concentration of and activated complex that is formed from the reactants. The reactants must be activated by means of an activation energy to form the activated complex before they can be converted into products. The activated complex is a transient state; an unstable complex held together by weak bonds. Therefore, the activation energy, according to this theory, is crucial to form the activation complex to be converted into products.
What is the relationship between an energy diagram and activation energy in a chemical reaction?
An energy diagram shows the energy changes that occur during a chemical reaction. Activation energy is the minimum amount of energy required for a reaction to occur. In the energy diagram, the activation energy is the energy barrier that must be overcome for the reaction to proceed. A higher activation energy means a slower reaction, while a lower activation energy means a faster reaction.
How does orientation and the activated complex affect a reaction?
Orientation affects the likelihood of successful collision between reactant molecules, increasing the chance of forming the activated complex. The activated complex is a high-energy, unstable intermediate state in a reaction, which is crucial for the reaction to proceed and for products to be formed. The orientation of molecules influences how effectively they can overcome the activation energy barrier to form the activated complex and progress to product formation.
What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.

What is the relationship between temperature and the activation energy on a graph?
On a graph, the relationship between temperature and activation energy is typically shown as an inverse relationship. As temperature increases, the activation energy required for a reaction decreases. This is because higher temperatures provide more energy to molecules, making it easier for them to overcome the activation energy barrier and react.
How is activatiokn energy represented on an energy diagram?
Activation energy is represented as the energy difference between the reactants and the transition state on an energy diagram. It is the energy barrier that must be overcome for a chemical reaction to occur. The activation energy is depicted as the peak of the curve on the reaction pathway.
What Activation energy play in a chemical reaction?
It indicates how likely a reaction might be, but there are no hard rules. Low activation energy indicates that the reaction is likely to take place spontaneously. In most cases, the reaction must be exothermic as well. There are lots of exceptions to these simple rules. For any reaction to occur, the reactants must gain at least the activation energy.
