How Can I Accurately Measure the Rate of Reaction in Homogeneous Catalysis?

Click For Summary
SUMMARY

The discussion focuses on measuring the rate of reaction in homogeneous catalysis using two primary methods: pH change and optical property measurement. Participants suggest that measuring pH change with a pH meter is the simplest approach, while optical measurements may offer greater accuracy but introduce complications such as temperature control. The feasibility of each method depends on the specific reaction and catalyst involved, with emphasis on selecting a reaction that exhibits a significant pH change for effective measurement.

PREREQUISITES
  • Understanding of homogeneous catalysis principles
  • Familiarity with reaction kinetics
  • Knowledge of pH measurement techniques
  • Experience with optical property analysis methods
NEXT STEPS
  • Research methods for measuring optical properties in chemical reactions
  • Explore various catalysts suitable for pH change measurement
  • Study temperature control techniques in reaction kinetics experiments
  • Investigate alternative methods for measuring reaction rates, such as spectrophotometry
USEFUL FOR

Chemists, researchers in reaction kinetics, and students studying homogeneous catalysis will benefit from this discussion, particularly those looking to accurately measure reaction rates using pH or optical methods.

I'm studying homogeneous catalysis and reaction kinetics, and I want to conduct an experiment that measure the rate of reaction by either:

1. a pH change​
or
2. consumption or generation of a compound bearing optical properties.​

Which one is more feasible? Hopefully you'll suggest a nice reaction.

What other ways can I experimentally measure the rate of reaction accurately (besides pressure change for 2H2O2 -> 2H2O + O2)?

For option 1) simply measure the pH change using a pH meter, this would probably be the simplest approach.
 
I think measuring the optical properties will be more accurate, but there will certainly be complications involved in keeping the reaction at constant temperature, etc.

so measuring pH change will be more simple. Is there a reaction that comes to your mind?

Thnx in advance for helping me :)
 
not exactly, I though that perhaps this was specified in your assignment. If the reaction does not involve significant trend in pH change, then obviously you'll have to consider another method. It all depends on which catalyst you have in mind or were assigned.
