You are enjoying a 49ers football game all afternoon and now it's time to go home. You and many other fans get outside the stadium only to find there are no taxis available and you realize the available UBERs will take at least 30 minutes to get there. Therefore, you have to wait. Comparing this zero transport scenario to enzyme reaction rates in your body, it illustrates how reaction rates are affected by:

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

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.
