At 100°c pure gaseous a reacts with stoichiometry 2a batch reactor as follows: p in a constant volume pa (atm) t (sec) 0 1 2 0.38 0.18 40 0.08 0.04 60 80 (a) by plotting the appropriate graph, show that the reaction follows first order kinetics and find the rate constant for the reaction. graph paper is available. [10 marks] (b) what size plug flow reactor operating at 100°c and 1 atm can treat 100 kmols a h1 to obtain a 95% conversion of a? use the rate constant determined in part (a) [10 marks] (c) comment on the answer obtained from (b). is this volume feasible? what could be done to reduce the reactor volume?

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.
