Homework Help Overview
The discussion revolves around calculating the vacancy concentration in Zinc at a temperature of 687K, using the activation energy for vacancy formation. The original poster presents an equation for vacancy concentration but encounters issues with the exponent term resulting in zero.
Discussion Character
- Exploratory, Assumption checking
Approaches and Questions Raised
- The original poster attempts to apply the formula for vacancy concentration but questions the validity of their unit conversions and the expression of activation energy. Other participants suggest that the activation energy should be expressed per vacancy rather than per mole, and they discuss the implications of unit consistency.
Discussion Status
Participants are exploring different interpretations of the activation energy's units and how they relate to the formula. There is a suggestion that dividing the activation energy by Avogadro's number could resolve the unit mismatch, and some participants confirm this approach.
Contextual Notes
The original poster is working under the constraints of a homework assignment, which may impose specific requirements for unit usage and calculations. There is an ongoing examination of the assumptions regarding the activation energy's expression.
