What is the relationship between temperature and the rate law of a chemical reaction?
The relationship between temperature and the rate law of a chemical reaction is that an increase in temperature generally leads to an increase in the rate of the reaction. This is because higher temperatures provide more energy for the reacting molecules to overcome the activation energy barrier, resulting in a faster reaction rate.
What factors influence the activation energy of a chemical reaction?
The factors that influence the activation energy of a chemical reaction include temperature, concentration of reactants, presence of a catalyst, and the nature of the reactants and their bonds.
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.
What is the relationship between temperature and the shape of the Gibbs free energy curve in a chemical reaction?
The relationship between temperature and the shape of the Gibbs free energy curve in a chemical reaction is that as temperature increases, the curve becomes flatter and broader. This is because higher temperatures increase the kinetic energy of molecules, making it easier for the reaction to occur, resulting in a lower activation energy and a more spread out curve.
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 do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.

How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added

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.
On what does activation energy depend?
Activation energy depends on the specific chemical reaction taking place. It is influenced by factors such as the nature of the reactants, temperature, and presence of catalysts.
How does activation energy affect chemical reactions?
The Arrhenius equation is: Ea = -RT ln(k/A) where Ea - activation energy R - universal gas constant ln - logarithm k - speed constant T - temperature in kelvins
What is a non example of a activation energy?

How do changed in temperature and activation energy compare in how they affect reaction rate?
Changes in temperature and activation energy have opposite effects on reaction rate.
