Transcript of 06.05 Rate and Collision Theory

A specific catalyst was not provided for this reaction, but catalysts are useful for increasing the rate of many slow reactions. In your own words, give a detailed explanation of how catalysts can increase the rate of a reaction or process.

Example

When you need to start a fire and the wood is taking too long to catch on fire. You can use some lighter fluid to start the fire.
The fluid is the catalyst. It sped up the process of the fire.
What two factors did you investigate in your procedure, and why did you choose to compare these two factors?
The two factors I chose to compare are temperature vs. Alka-Seltzer. They are the most simple & most effective factors I thought of.
What was your prediction about the results of each factor tested in your two lab procedures? Explain your predictions based on your knowledge of the dissolving process, collision theory, and reaction rates.What was your prediction about the results of each factor tested in your two lab procedures? Explain your predictions based on your knowledge of the dissolving process, collision theory, and reaction rates.
I predicted that the Alka-Seltzer will increase the reaction rate in these two lab procedures. This is because when alka-seltzer dissolves into a liquid, such as water, there is a bubbling reaction. This will be a very rapid reaction, thus expressing the reaction rate as fast, due to the immediate reaction when compounded. If there is a need for a catalyst, there can be stirring of the solution.
In your own words, explain the collision theory, and what is necessary for a collision to be successful.
In order for a reaction to be successful, particles most collide together. To achieve this "sufficient energy and correct orientation—must be true for a given collision to successfully result in the production of products".
What other factors did you need to control during your investigation? Explain how you controlled each one in your procedure.
06.05 Rate and Collision Theory
I needed to control the amount of water, temperature, the number of Alka-Seltzers I wanted to use and how fast it dissolved by changing certain things.
