Under these conditions, will the pressure of NOCl tend to rise or fall? rise fall Is it possible to reverse this tendency by adding Cl2? In other words, if you said the pressure of NOCl will tend to rise, can that be changed to a tendency to fall by adding Cl2? Similarly, if you said the pressure of NOCl will tend to fall, can that be changed to a tendency to rise by adding Cl2? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of Cl2 needed to reverse it. Round your answer to 2 significant digits.

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.
