Reaction Rate Constant and Specific Rate Constant are two terms used to describe the kinetics of a chemical reaction. These terms are different from each other and have different definitions and functionality. The reaction Rate Constant is a constant that relates the response rate to factors such as concentration, temperature, and the presence of a catalyst.
Main Difference
Specific Rate Constant, on the other hand, is a constant that relates the reaction to the attention of reactants. The rate law describes it for the response. In detail, let us discuss the significant differences between Specific Rate Constant and Reaction Rate Constant.
What is the Reaction Rate Constant?
Reaction Rate Constant is a proportionality constant that relates the rate of a chemical reaction to various factors such as the presence of a catalyst, temperature, and concentration. The reaction Rate Constant can be expressed in units of s^-1 or M^-1s^-1. This constant depends on the specific conditions of the reaction and can change with changes in these conditions. Moreover, it is crucial to understand a chemical reaction’s mechanism and behavior.
What is a Specific Rate Constant?
A specific Rate Constant is a proportionality constant that relates the rate of a chemical reaction to the concentration of a reactant; The rate law defines it for the response. The proportionality constant of the Specific Rate Constant is one mole/dm^3.
Moreover, it is independent of the concentration of the reactants. Factors such as the presence of the catalyst, temperature, and nature of reactants influence it. Furthermore, the Specific Rate Constant is used to determine the rate of a reaction under specific conditions.
Key differences between Reaction Rate Constant and Specific Rate Constant
- The specific Rate Constant is independent of the concentrations of the reactants. The reaction Rate Constant, conversely, is dependent on the particular conditions.
- A specific Rate Constant is essential for optimizing reaction conditions for a desired outcome; at the same time, Reaction Rate Constant plays a critical role in understanding the behavior and mechanism of a chemical reaction.
- The reaction Rate Constant depends upon the concentration and temperature, while Specific Rate Constant depends only on temperature.
- The nature of the reactants influences the Specific Rate Constant. The essence of reactants does not affect the Reaction Rate Constant.
- The reaction Rate Constant is used to describe the overall kinetics of a reaction. A sOn the flip side, Specific Rate Constant is used to resolute the reaction rate under particular conditions.
