what is value of rate constant at extremely high temperature? is this rate constant feasible?why or why not?

Expert Answer:

The formula that describes the temperature dependence of the rate constant is attributed to Arrhenius, but is a consequence of our arguments above:

 

The temperature dependence of the absolute rate constant appears to depend on two quantities (A and Ea), whereas the relative rate constants at two temperatures depend only on one quantity (Ea).

The A factor is equal to the high temperature limiting rate constant for the reaction. This can be seen by inserting a very large (infinite) temperature into the Arrhenius equation above. This is true because at very high temperature, ALL the molecules have enough energy to react, but they must have a collision and the proper geometry even so.
