16. 2 Activation Energy (Arrhenius Equation) from studylib.net

It is an important parameter in many fields and applications, as it represents an estimate of the resistance to chemical transformation (hence it is important for catalysts). A slight rearrangement of this equation then gives us a straight line plot ( y = mx + b) for ln k versus , where the slope is : When the lnk (rate constant) is plotted versus the inverse of the temperature (kelvin), the slope is a straight line.

The Activation Energy Is The Minimum Energy Required To Initiate A Reaction.

The activation energy can be calculated from the reaction rate constant, which changes. We can graphically determine the activation energy by manipulating the arrhenius equation to put it into the form of a straight line. All above answers are wrong.

Taking The Natural Logarithm Of Both Sides Gives Us.

The slope for the line represents the negative quotient for activation energy (ea) over the gas constant (r). T 1 and t 2 = absolute temperatures (kelvin) k 1 and k 2 = the reaction rate constants at t 1 and t 2. We can use the arrhenius equation to relate the activation energy and the rate constant, k, of a given reaction:

This Is A Graph Of Ln (K) Versus 1/T.

The activation energy can be determined by finding the rate constant of a reaction at several different temperatures. The activation energy is equal to the difference between the threshold energy needed for the reaction and the average kinetic energy of all the reacting molecules. A slight rearrangement of this equation then gives us a straight line plot ( y = mx + b) for ln k versus , where the slope is :
