Irreversible Uncatalyzed Reactions: 1st Order
Description | Implementation | Examples
Description
The model presented here simulates the kinetics of an uncatalyzed, irreversible 1st order chemical reaction. In this reaction, all substrate initially present is converted to product since no back-reaction is allowed. By solving the ordinary differential equations describing the process, the time course of the reaction can be seen directly. Further analysis of the initial velocity of the reaction will enable us to appreciate the problems encountered in the real world in determining actual rates of reaction.
Assumptions
The following are assumed by this model:
- The reaction is occurring in a well-mixed system.
- The temperature of the system is constant.
- The volume of the system is constant, which allows the use of concentrations in the rate laws.
