Activation energy describes the energy that is required to get chemical reactions started.
The theory that life started itself from the chemical properties of matter is called abiogenesis. Abiogenesis proposes that living organisms can arise from non-living matter through natural processes such as chemical reactions.
If what you get is the same, chemically, as what you started with, then no, it's not a chemical reaction (be careful to take side effects into account: a series of reactions can yield the same molecule you started with, but make changes in other molecules in the process). If it's not chemically identical, then even if the properties are similar, it IS a chemical reaction.
Chemical change because its form is a new state then what it was when it started (:
If your question is ''What causes the activation energy required in a chemical reaction to lower down?'' Then my answer to your question would be that the temperature factor is either more than to what the enzymes needed or less than what is needed by the enzymes to function. However the optimum temperature mostly for an enzyme to be active at the fullest can be till 40 degrees Celsius.
Its a chemical change. Chemical changes produces a new substance while physical change does not Examples of physical change are ripping paper, breaking a bottle and melting ice. Examples of Chemical change are cooking macaroni, rusting iron and mixing acids and bases to make salt and water

All chemical reactions need a certain amount of activation energy to get started.

when something undergoes a chemical reaction, its properties may change. meaning the properties could be different than whhat they started off as.

They are chemical substances which are different from those that you started with.
The amount of energy needed to start a chemical reaction is known as the activation energy. This energy is required to break the existing bonds in the reactants before new bonds can be formed in the products.
my 307cc if started in gear pulls away no revs required even up hill
