By studying thermodynamics and kinetics , we can draw a lot of conclusions about a reaction and how we can control them.
Thermodynamics is the study of transformations of energy. It is only concerned with the energetic and the position of the equilibrium in a reaction.
It has nothing to say about how fast the equilibrium is reached. This question is the domain of kinetics. Overview and Key Difference 2. What is Reaction Rate 3. Reaction rate or rate of reaction is the measure of how fast or slow a chemical reaction occurs in the conversion of a reactant into a product while a reaction rate constant gives a comparative amount of the reaction rates of reactants and products.
The rate of reaction is influenced by the types of reaction. These are the types of reaction, the concentration, pressure, and the temperature when the reactions occurs. The reaction rate constant is influenced by the temperature as well as the catalyst. The reaction rate constant will remain constant only if what is changed is the concentration of reactants otherwise it will change much like the rate of reaction. Units in a reaction rate constant are dependent upon the order of the reaction while they are not in a rate of reaction.
Difference Between Rate and Rate Constant. Difference Between Similar Terms and Objects. MLA 8 M, Emelda. Name required. Apart from that, there are some important conditions needed for a chemical reaction to proceed until the completion. Such of these conditions include proper temperature and pressure, ionic strength, etc. However, each and every chemical reaction can be explained using the two terms: the rate of reaction and rate constant.
The rate of reaction describes the rate at which the reaction proceeds and rate constant quantifies the rate of a reaction. The main difference between rate of reaction and rate constant is that rate of reaction is the change of the concentration of reactants or the change in concentration of products per unit time whereas rate constant is the proportionality constant related to the rate of a particular reaction.
The rate of reaction or the reaction rate is the change in the concentration of reactants or the change in the concentration of products per unit time. This can be obtained by two ways. One is by dividing the concentration of reactants consumed during the reaction from the time elapsed for that consumption.
The other method is by dividing the concentration of products formed at the end of the reaction from the time elapsed for that formation. This can be shortened as below.
