the interval between stimulation and response.

PE Theory definition: Reaction time is the name given to the ability to react quickly to an action e.g: reacting to the sportsgun being fired at the begining of a race.Scientific defintion: The time elapsed between a stimulus and an the response to it ( the effector).
A product, by definition a product is produced by a chemical reaction.
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
A chemical reaction, by definition, does not require air unless one of the constituents of the reaction is intended to be supplied by it.

definition of time sampling
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
In chemistry, the half-life of a reaction is defined as the time needed for the concentration of a reactant to decrease to half of its initial concentration. According to that definition, the half-life of the reaction will be t1/2 = 0,693/k where k is the equilibrium constant for that reaction at a specific temperature.
