Homework Help Overview
The problem involves the equilibrium between the release and decay of Kr-85 in the atmosphere, specifically focusing on the mass of Kr-85 that would result in a decay rate equal to the daily release of 2.0 grams by a power plant.
Discussion Character
- Exploratory, Conceptual clarification, Mathematical reasoning
Approaches and Questions Raised
- Participants discuss the relationship between the decay constant and the activity of Kr-85, questioning whether the release is instantaneous or continuous. There is mention of the half-life of Kr-85 and the need to find a mass that allows for a decay rate of 2 grams per day.
Discussion Status
Some participants have provided insights into the relationship between activity and the number of atoms present, suggesting that the average activity can be converted to the number of decaying atoms. There is an ongoing exploration of the relevant equations and concepts, but no consensus has been reached on a specific method or solution.
Contextual Notes
Participants note the lack of explicit information regarding whether the release of Kr-85 is instantaneous or continuous, which may affect the calculations. The original poster expresses uncertainty about the appropriate equations to use given the nature of the decay function.
