Title: Qualitative Kinetics Factors that influence the rate of reaction.
Objective: In industrial synthesis and manufacture, for instance, a chemical equation
that seems extremely promising on paper can turn out to be so slow in plant operation
that a business would be unable to profit from its utilization. On the other hand, it is
frequently necessary to slow down extremely exothermic reactions to stop energy from
evolving at an explosively rapid rate. These chemists need to be aware of their options
for modifying reaction rates.
Results:-
A. Reactant concentration:
Balance chemical equation: 𝑀𝑔(𝑠)+ 2𝐻𝐶𝑙(𝑎𝑞)→ 𝑀𝑔𝐶𝑙2(𝑎𝑞)+ 𝐻2(𝑔)
[HCl] Total Mass of Mg Reaction Time
0.75 M 0.024g 19.15 sec
1.5 M 0.024g 18.50 sec
3M 0.014g 15.55 sec
6M 0.026g 16 sec
What happens after the reaction: during the experiment, the solid Mg will disappear and
turn into an aqueous MgCl2 solution, and we can also see the H2 as a gaseous form as
shown in the equation. We also noticed that as the concentration of HCl increases
regardless of the error in mass of Mg, we can predict that reaction time will increase.
This happens because a reactant will collide more often in a given time period at a
higher concentration.
