TUGAS KIMIA LAJU REAKSI

Let me introduce myself, my name is Kumang Andiratama. My name is Rafshin 22, from class F2. Here I will explain about the speed of reaction. What is the speed of reaction? The speed of reaction is the change in the concentration of reactants or products over time. Factors of speed of reaction. There are several factors that affect the speed of reaction. That is, concentration. The higher the concentration of a substance, the more molecules of reactants are available. That makes it possible for the reaction to grow even faster. The second factor is surface area. If the reactants have a wide surface, the friction between the particles will occur more often. This is what makes the reaction go faster. The third factor is temperature. If the temperature of a reaction is increased, it causes the particles to move more actively. The growth will occur more often and cause the reaction to go faster. The last factor is catalyst. The catalyst plays a role in reducing activation energy. So, with the presence of a catalyst, a reaction can go fast. From these explanations, it can be known that the factors of speed of reaction affect the speed of a reaction. Examples of speed of reaction. Examples of speed of reaction in everyday life are in the process of making bread. The dough will be added more to make it faster. The use of flour in the process of making bread dough is one of the examples of the use of catalyst. In the process of accelerating the formation of the dough, the cake is smooth and develops. That's all from me. Thank you.
