A) The concentration of DCPIP in the solution will increase exponentially.
B) The absorbance at 60 minutes will be roughly equal to 1.4.
C) The change in absorbance over time in the solution will be less than that of the other samples.
D) The temperature of the solution will exceed 75o C.
Answer: C) The change in absorbance over time in the solution will be less than that of the other samples.
