Answer #1

Ans. The reaction of the Hydrogen peroxide with Catalase will result in breaking down of the Hydrogen peroxide into oxygen and water as oxygen being a gas wants to escape liquid by oxygen bubbles and thus forms Foams.

Rection :

2H2O2 + Catalase (in presence of)   2H2O + O2

This test to demonstrate the presence of Catalase enzyme. This test is used to distinguish bacteria those who produce catalase and those who not. The 2 bacterial genera such as staphylococci is differentiated from the non-catalase producing bacteria such as streptococci.

The activation energy for the decomposition of hydrogen peroxide is 55.0 kJ/mol. When the reaction is catalyzed by the enzyme catalase, it is 11.00 kJ/mol. 2H2O2(aq) → 2H2O(l) + O2(g) Calculate the temperature that would cause the nonenzymatic catalysis to proceed as rapidly as the enzyme-catalyzed decomposition at 20.0°C. Assume the frequency factor, A, to be the same in both cases. Report your answer to 3 significant figures.
