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 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.
How do changes in temperature and activation energy compare in how they affect reaction rate Apex?
Changes in temperature and activation energy have opposite effects on reaction rate.
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.
Will affect the rate of the constant according to the Arrhenius equation changing which factors?
The rate constant in the Arrhenius equation is impacted by temperature and activation energy. Increasing temperature generally increases the rate constant as molecules have more energy to overcome activation barriers. Similarly, lowering the activation energy required can lead to a higher rate constant.
How is activation energy related to bond energy?
Activation energy is the minimum energy required for a chemical reaction to occur. It is related to bond energy because breaking chemical bonds and forming new bonds requires energy, which contributes to the activation energy of a reaction. Bonds with higher bond energy are more stable and require more energy to break, hence increasing the activation energy of the reaction.
Can a reaction have zero activation energy?
No, all reactions require some activation energy to proceed, even if it is very small. Activation energy is the minimum amount of energy required for reactant molecules to transform into product molecules.
What happens to the reaction rate if the activation energy gets smaller?
If the activation energy decreases, the reaction rate typically increases because a lower activation energy makes it easier for the reactant molecules to overcome the energy barrier and form products. This allows the reaction to proceed more rapidly at a given temperature.
Is heating a flask on a hot plate an example of activation energy beginning to react?
No, heating a flask on a hot plate is not an example of activation energy beginning to react. Activation energy refers to the minimum amount of energy required for a chemical reaction to occur, and it is not related to heating a flask. Heating a flask on a hot plate simply refers to the process of applying heat to the flask, which can facilitate a reaction by increasing the temperature and providing the necessary energy for the reaction to proceed.
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.
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.
