Question
2.) if instead of using the blue dye, we had used a red dye, what changes would you make in your experimental procedure to determine the rate law for the oxidation of the red dye by sodium hypo-chloride? 3.) if the experiment were carried out at 40C rather than at room temperature, what differences would you expect to observe? would the order of the reaction change with respect to the dye? Would the rate constant change? 4.) A and B are 2 species which react in the presence of an acid catalyst. A + B --> Products Catalyst increase reaction rates by providing an alternative mechanism with lower activation energy. Do you expect the catalyst to appear in the rate law?Explanation / Answer
2.) if instead of using the blue dye, we had used a red dye, what changes would you make in your experimental procedure to determine the rate law for the oxidation of the red dye by sodium hypo-chloride?
Answer: IF we are performing the experiment with the help of UV-vis sepctrophotometer then we will change the wavelength at which experiment is carried out to observe the rate.
3.) if the experiment were carried out at 40C rather than at room temperature, what differences would you expect to observe? would the order of the reaction change with respect to the dye? Would the rate constant change?
Answer: If we are increasing the temperature, then rate of reaction will increase. The rate constant will increase. There will be no effect on the order of reaction.
4.) A and B are 2 species which react in the presence of an acid catalyst. A + B --> Products Catalyst increase reaction rates by providing an alternative mechanism with lower activation energy. Do you expect the catalyst to appear in the rate law?
Answer: No the catalyst is never involved in the rate determining step. It just alter the pathway of the reaction.
