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.

What does it take to break chemical bonds?
Chemical reactions occur if the overall energy of the system is lowered and / or if the overall disorder of the system is increased.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
What happens to the reaction rate if the activation energy gets smaller?
When activation energy is lowered (e.g. by using a catalyst) the reaction rate increases (at the same temperature)
Which statement defines activation energy?
Activation energy is defined as the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction. That means the energy required to activate atoms or molecules.
Can boiling point of acetone be lowered if placed in a vacuum?
yes. it will be lowered.
What is lowered to speed up a chemical reaction?
Activation energy is lowered to speed up a chemical reaction.
According to collision theory what best explains how a catalyst increases the reaction rate for a chemical reaction?
A catalyst decreases the threshold energy for a chemical reaction. A catalyst decreases energy required for two particles to react. A catalyst lowers the amount of energy needed to reach the transition state.
Why does molarity goes down if water is added to the chemical reaction?
Because the concentrations of solutes are lowered.
Why does adding more water slow down the rate of a chemical reaction?
The concentration of reactants is lowered.
What is the truth about catalysts?
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
Why do they put salt on snow?
The salt and water create a chemical reaction which causes the waters' temperature to be lowered so reducing its freezing point.
Why it is necessary to Lowe rthe activation energy?
It speeds up/catalyzes the rate of reaction. Thus the agents are called catalysts (mainly enzymes and transition metals). The existence of life depends on controlled chemical reactions, and if the activation energy is not lowered then much more energy is required to carry out the reaction. These chemical agents provide a partial substitute for energy because energy has limited availability.
An enzyme is a special kind of catalyst that works to do what?
speed up chemical reaction because of the lowered activation energy
Which would react more quickly in a chemical reaction a single sugar cube or an equal mass of graduated sugar crystals?
When the granules dimension of a material is lowered the surface area is increased and the reaction rate is higher.
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 are situations that can effect the rate of a chemical reaction?
In a typical chemical reaction, xA + yB --> zC, the rate can be expressed as: Rate = k (T) * [A]^x * [B]^y where k = Rate constant, a function of temperature [i] = molar concentration of reagent i So, chemical reaction rate is affected by temperature and reagent concentration. Thus any variable that affects temperature (e.g. pressure or volume in the case of gases) will also affect reaction rate. However, the rate constant k is also a function of activation energy, the energy required to drive the reagents to the point where the reaction must proceed to completion. This activation energy can be lowered by the presence of a catalyst. Thus the presence of a catalyst can also affect the reaction rate.
Under a fractional reserve banking system the amount of money loaned out can only increase if what happens?
The required reserve ratio is lowered.
