The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate of a chemical reaction.
The mitochondria changes food energy to chemical energy.
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
In an exothermic chemical reaction, heat is released to the surroundings. This results in an increase in temperature, which can be observed as a rise in temperature of the surroundings. Additionally, the products of the reaction typically have lower energy than the reactants.
Because the changes are brought about by adding some form of energy, whether it is temperature, pressure, or radiation waves.
Changes in temperature can speed up or slow down chemical reactions by affecting the kinetic energy of molecules. Higher temperatures generally increase the rate of reactions by providing more energy for molecules to collide and react. However, extreme temperatures can also denature proteins and disrupt the equilibrium of a reaction.
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
The enthalpy temperature dependence influences the overall energy changes in a chemical reaction by affecting the heat absorbed or released during the reaction. As temperature increases, the enthalpy change also changes, which can impact the reaction's energy balance.
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate 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.

In a chemical change, energy is either absorbed or released. This can result in changes in temperature, light production, or other forms of energy transfer during the reaction.
The body changes chemical energy to mechanical energy to power muscle contractions and movement.
Energy is required to break chemical bonds in reactant molecules in order to initiate a chemical reaction. This initial input of energy is called activation energy. In addition, energy is released or absorbed during a chemical reaction, which can result in changes in temperature.
