1a. A student claims that the reaction is first order with respect to F2(g). Do you agree or disagree? Justify your answer using the data above. 1b. What is the initial rate of disappearance of F2(g) in trial 3? Justify your answer.

2a. Calculate the average rate of disappearance of NH3 between 0 and 1.54 x 10^2 s. Use this calculated rate to determine the rate of appearance of H2 over the same time period.
2b. What are the rates of disappearance of NH3 ad rate of appearance of H2 between the times 1.54 x 10^2 and 4.83 x 10^2 s?

1. they vary with a higher number because boiling is way hotter than melting

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.
