Importance Of Chemical Kinetics
A reaction is defined by its reactants and products, whose identity must be learned through experiment. Chemical kinetics is the area of chemistry that concerns reaction rates. One main goal of chemical kinetics is to understand the steps by which a reaction takes place. These series of steps are called the reaction mechanisms. Chemical kinetics deals with the speed at which these changes occur. The speed, or rate, of a process is defined as the change in a given quality over a specific period of time. For chemical reactions, the quality that changes is the amount or concentration of a reactant or product. So, the reaction rate is defined as the change in concentration of a reactant or product per unit time.
RATE= concentration of A at a time t2-concentration of A at a time t1t2-t1 RATE=At
The symbol indicates the change in a given quality and Ameans concentration of A in mol/ L. The change can be a positive or negative, thus leading to a positive or negative reaction rate. Instantaneous rate can be obtained by computing the slope of a line tangent to the curve at that point. The activation energy is the energy needed to start. The faster the molecules move, the harder they hit. In some cases there can be a limiting rate which is the slowest step and uses the most activation energy. …show more content…
Forward reactions are composition reactions, which are certain types of chemical reactions. Reverse reactions are decomposition chemical reactions. When reverse reactions are neglected the rate law kAnis used. So, when the forward reactions are neglected the rate law kBmis used. The integrated rate law of the concentrations depends on the time. All this allows us to know is the steps taken in a chemical reaction. The rate of reaction depends on the concentration just like how to integrated rate law of the concentrations depends on the time. Some things that affect the rate
