One can think of the Activation energy as the magnitude of the potential barrier that separates the minima of the potential energy surface and the final thermodynamic state. Also, it is the minimum energy that a system must possess for enabling the reactions ofmoleculesto the expected products. ...

Hydrocarbons have covalent bonds; so does oxygen. To start the combustion reaction, the bonds present in these molecules must be broken. That requires energy called activation energy. Once the reaction starts, the energy released is sufficient for the combustion to proceed....
The activation energy (Arrhenius equation) was 11.220 kJ/moL for HMF, 36.957 kJ/moL for hydroperoxide and 50.536 kJ/moL for the formation of secondary products derived from lipid oxidation, 43.388 kJ/moL for loss of vitamin A, 51.960 kJ/moL for degradation of Vitamin C and 92.361 kJ/moL ...

What is phosphate used for? Phosphates are used for the activation of proteins to make them perform specific functions. One phosphate group combines with another phosphate group and an organic molecule to form an energy molecule. Phosphate acts as a buffer. In about 85% of the human body, pho...
Find the rate coefficient at 273 K for the decomposition of nitrogen dioxide, which has the reaction: 2NO2(g) → 2NO(g) + O2(g) You are given that the activation energy of the reaction is 111 kJ/mol, the rate coefficient is 1.0 x 10-10 s-1, and the value of R is 8.314 ...
F = 9/5C+ 32 It is easy to convertCelsius to Fahrenheitby following these two steps: Multiply your Celsius measurement by 1.8. Add 32 to the result. The final answer will be the temperature in degrees Fahrenheit. Note: If you are doing temperature conversions for a homework problem, take...
