Observations and Questions
[1] Sample Calculation: Show your enzyme reaction rate calculation for Trial 1.
[2] Convert enzyme concentrations of 2.5%, 5.0%, and 10% to ppt units.
[1] As given in the question for trial 1
Oxygen concentration change data(ppt) = 4.23
Elapsed time(s) = 20
So to calculate enzyme reaction rate, we have to use the formula
Rate of reaction(ppt/s) = amount of concentration change/elapsed time
= 4.23/20
=0.21
[2] To convert the enzyme concentration of 2.5% , 5% and 10% we just have to divide the concentration levels by 100
For e.g,
(1) 2.5% = 2.5/100 = 0.025 ppt
(2) 5% = 5/100 = 0.05 ppt
(3) 10% = 10/100 = 0.1 ppt

In this lab we will be expressing rate as a change in
concentration of reactants over time. In order to calculate this,
we need to know the initial concentrations of our reagents after
they are combined but before the reaction occurs. This is a
dilution process. Recall that the calculation for a dilution is
accomplished using the relationship M1V1 = M2V2.
