In this experiment it is assumed that the temperature of air in a closed flask is the same as the temperature of the water bath in which the flask is submerged. As the temperature of the water bath changes will this assumption still be valid and under what conditions will it be valid? Please explain.

How many moles are in 7.2 x 10^23 carbon molecules?

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?
