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 : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
