Complete Question

The complete question is shown on the first uploaded image

Part A

    activation barrier for the reaction

Part B

    The frequency plot is      

Explanation:

From the question we are told that

     at    

and  at    

The  Arrhenius plot is mathematically represented as

Where is the activation barrier for the reaction

         R is the gas constant with a value of  

Substituting values

=>      

The  Arrhenius plot can also be  mathematically represented as

Here we can use any value of k from the data table with there corresponding temperature let take  

So substituting values

=>          

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
