Understanding Chemical Kinetics: Troubleshooting Common Questions in the Lab

AI Thread Summary
The discussion centers on troubleshooting a kinetics lab, specifically addressing three key questions about determining the order of reactions with respect to HCl and Sodium Thiosulfate, and the inadequacy of rate values for calculating the rate constant k. The participant has created a graph plotting Rate (1/time) against initial concentration of HCl to analyze reaction order. They seek guidance on interpreting the graph and the next steps for their analysis. Additionally, clarification is needed on why the rate values may not provide an accurate k value. Assistance is requested to better understand these concepts and improve the lab results.

I am having a problem with my kinetics lab. There are just three questions I can not understand.
1. Determine the order with respect to HCl. Explain.
2. Determine the order with respect to Sodium Thiosulfate. Explain.
3. Why rate values for this experiment not adequate to achieve an accurate value for k?

It was a lab with two tables, and the tables are here:

No equations.. Just explaining.



I made a graph for problems 1 and 2, Rate (1/time) vs [HCl]0.. Am I going the right direction? What would I do after that? I have no idea for question 3.. I sincerely thank those that take the time to read and help. your help is greatly appreciated. Thank you!

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...

Thread 'How to find the pH of a galvanic cell (MIT OCW problem set)'

This is the final problem in this problem set from MIT OCW. Here is what I did to try to solve it The table cited in the problem is below We can easily spot the two redox couples that are in the electrochemical cell we are given. The hydrogen-based electrode has standard potential zero, and the silver-based electrode has standard potential 0.22. Thus, the hydrogen electrode, with the lower potential, is the reducing agent (ie, it is where oxidation happens) and is the anode. Electrons...
