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, you need to determine the change in quantity of a reactant or product over a specific period of time.
In this case, it seems like the rising of the paper disc is the reaction you're observing. To calculate the rate of this reaction, you can use the formula:
Rate of reaction = (1/t)
where t is the time it took for the paper disc to rise from the bottom of the beaker to the surface.
So, based on the information you provided, the rate of reaction would be:
Rate of reaction = (1/0.83 seconds)
This will give you the rate of the reaction in inverse seconds.
Regarding the formula you mentioned, (1/q) ( (d[Q])/(dt) ), it seems to be a more general expression for reaction rates. However, in this specific case, the rate of reaction can be simply calculated using (1/t).
Note that reaction rates can also be calculated based on the change in the concentration of reactants or products over time, if that information is available. In your case, if you have the concentration of the reactants or products at different time points, you can use the formula:
Rate of reaction = Δ[Q]/Δt
where Δ[Q] represents the change in concentration of a reactant or product, and Δt represents the change in time between those concentration measurements.
