POST-LAB QUESTIONS
1. What would happen if you added more than 5 mL of
yeast solution to the H2O2?
2. What would happen if you added more than 5 mL of
H2O2 to the 5 mL of yeast solution?
Homework Answers
Solution:
1) When we added more than 5 mL of yeast solution in H2O2, then the rate of decomposition of H2O2 increases.
H2O2 decomposes in the presence of an enzyme catalase (found in yeast), as:
2H2O2 (in the presence of catalase) = 2H2O + O2
2) If we added more than 5 mL of H2O2 in 5 mL of yeast solution, then rate of decomposition will be decreases because all the available active sites of catalase enzyme have been blocked and hence, rate of decomposition decreases.
