(STEP 5: IRON)
Tare the balance. Put calorimeter (no lid) on the balance.
Measure the mass to the nearest 0.01 g
12.42 g
Use a graduated cylinder to add approximately 40 mL of
water to the calorimeter. Measure the mass of the
calorimeter (no lid) and water to the nearest 0.01 g.
52.66 g
Subtract to find the mass of the water. 40.24

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?
