What are the migration patterns of the current population?
Where are people moving from and where are they moving to? How fast is the population changing in different areas? These are important questions for people involved in deciding about where to build schools or hospitals or where to open new businesses. If an area is growing rapidly, action needs to be taken soon to accommodate the growth. How fast the growth is will determine how many schools to build. Rates of change affect a lot of decisions.
Rate Law and Specific Rate Constant
Consider a simple chemical reaction in which reactant
The rate of reaction is given by the change in concentration of
Since the rate of a reaction generally depends upon collision frequency, it stands to reason that as the concentration of
The proportionality between the rate and
- The rate law and specific rate constant are defined.
