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 activation energy and how do enzymes effect it?

There is no straight forward relation between enzyme and activation energy because although energy of reaction is fixed and is governed by laws of chemistry but for biochemical reactions concentration of enzyme and conc. of substrate affect rate of reaction and energy, but in general enzymes decrease activation energy of reaction.


How do enzymes affect the activation of energy in chemical reactions?

Enzymes lower the activation energy required for a chemical reaction to occur by providing an alternative pathway for the reaction to proceed. This facilitates the reaction to occur more readily and at a faster rate. Ultimately, enzymes speed up the reaction by lowering the energy barrier that needs to be overcome.


Why activation energy is referred in the definition of enzymes?

The chemical term activation energy is the amount of energy required for a chemical reaction to take place. For more information about different chemical contact a scientists or science professor in one's area.


What kind of energy do enzymes reduce?

Enzymes reduce activation energy, which is the energy required to start a chemical reaction. By lowering the activation energy, enzymes make reactions occur more readily and at a faster pace.


What is the effect that enzymes have on certain chemical reactions in living things?

Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.

What is the significance of the activation energy diagram in understanding chemical reactions?

The activation energy diagram is important in understanding chemical reactions because it shows the energy needed for a reaction to occur. It helps us predict reaction rates and understand how different factors, like temperature and catalysts, can affect the speed of a reaction.

What is the role of activation energy in inorganic chemistry?

Activation energy is the minimum amount of energy required for a chemical reaction to occur. In inorganic chemistry, activation energy determines the rate at which reactions proceed. Higher activation energy results in slower reactions, while lower activation energy results in faster reactions. By understanding activation energy, chemists can optimize reaction conditions and develop more efficient processes.


Do catalysts lower the activation energy of chemical reactions?

Yes, catalysts lower the activation energy of chemical reactions by providing an alternative reaction pathway that has a lower activation energy. This allows the reaction to proceed at a faster rate under milder conditions.
