From Wikipedia, the free encyclopedia. In chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, known as the rate determining step (RDS) or rate-limiting step.
Calculation of the activity rate i.e. the cost of each activity per unit of its relevant cost driver; Application of the cost of each activity to products based on its activity usage by the product. Cost Hierarchy. The first step in activity-based costing involves identifying activities and classifying them according to the cost hierarchy.
