I'm trying to calculated the rate of reaction
In this lab I took a 50 mL beaker and poured in 10 ml of cold distilled water into it, I then poured in 30 ml of original enzyme solution (I believed we used cold potato juice or something), I then took a piece of paper and placed it into a beaker of 40 Ml of 3.0% Hydrogen Peroxide solution, after waiting for 5 seconds i then took the 2.1 cm filter paper disc from the hydrogen peroxide and placed it onto a piece of paper, after draining for 10 seconds I then placed it into my solution of 10 mL of distilled of water and 30 mL of my enzyme solution at the bottom of the 50 mL beaker then removed the forceps i was using to hold the paper and timed the time it took for the paper to rise from the bottom of the 50 mL beaker to the surface and got .83 seconds, how do I calculate the rate of reaction
THANKS!!!!!
by the way I know
the formula is
(1/q) ( (d[Q])/(dt) )
I just don't know what to use for q and I'm guessing I use 3/4 for Q?

Additional Details
My teacher told me that the rate of reaction = 1/t which I think is just bs because that would be the frequency of the paper as it rose...
To calculate the rate of reaction in this case, you can use the formula:
rate of reaction = (1/q) * (d[Q]/dt)
Where:
- q represents the change in quantity or concentration of a reactant (or product) during the reaction.
- d[Q]/dt represents the change in quantity (or concentration) of the reactant (or product) with respect to time.
In your experiment, the paper disc rises in the reaction mixture due to the decomposition of hydrogen peroxide by the enzyme. To determine the appropriate value for q in this case, you need to consider what quantity is changing during the reaction.
Based on the information you provided, the paper disc rises due to the release of gas bubbles during the decomposition of hydrogen peroxide. Therefore, you can assume that the change in the volume of gas (or the number of gas bubbles) can be considered as q for this reaction.
However, without knowing the volume of gas produced, we cannot directly calculate the value of q. So instead, we can use an alternative approach to approximate the rate of reaction.
In your case, the time it took for the paper disc to rise from the bottom of the beaker to the surface can be considered as the reaction time. So, you can calculate the rate of reaction using the formula suggested by your teacher, which is:
rate of reaction = 1 / t
Where t is the reaction time in seconds.
Using this formula, you can calculate the rate of reaction for your experiment:
rate of reaction = 1 / 0.83 seconds ≈ 1.20 s^-1
Therefore, the approximate rate of reaction for your experiment is approximately 1.20 s^-1.
