Question

The enzyme catalase catalyzes the decomposition of hydrogen peroxide by the exothermic reaction

H_{2} O_{2} (a q) \to H_{2} O (l) + 1/2 O_{2} (g)

Part A Estimate the minimum detectable concentration of

H_{2} O_{2}

if a small amount of catalase (solid) is added to a hydrogen peroxide solution in a calorimeter. Assume that a temperature rise of

0.0 2^{\circ} C

can be distinguilshed You can use a heat capacity of

4.184 kJ kg^{- 1} K^{- 1}

for the hydrogen peroxide solution Assume the mass of water is

100 g

Express your answer using one significant figure and include the appropriate units.
