29 Apr Speed of reaction
Chemistry tuition classes in Miracle Learning Centre is very useful. If you do not understand chemistry, you must definitely attend the chemistry tuition class at Miracle Learning Centre. Let us learn about speed of reaction in this chemistry tuition lesson.
Your chemistry tuition teacher at Miracle Learning Centre will teach you about speed of reaction. Let us take a look at the reaction between hydrochloric acid and calcium carbonate. The rate of reaction can be measured by the rate of carbon dioxide produced. At the beginning, the speed of reaction is the fastest because there is a high concentration of reactants. Then the reaction slows down as the concentration of the reactants decreases. Finally, the reaction stops when one of the reactant is used up.
These are some of the factors that affect the speed of a reaction. The higher the concentration, the faster the rate of reaction. Larger surface area(powdered form) will increase the speed of reaction compared to a smaller surface area(crystal form). Increase in temperature also increases the speed of reaction. Increase in pressure causes an increase in the speed of reaction. Pressure only affects reactions involving gases. Addition of a suitable catalyst also increases the speed of reaction.
The student at Miracle Learning Centre asked, “How does the addition of a catalyst speed up a reaction?”
The chemistry tuition teacher at Miracle Learning Centre replied, “A catalyst is a substance that speed up a chemical reaction but remain chemically unchanged at the end of the reaction. Hence, a catalyst provides an alternative pathway for the reaction. This new pathway has a lower activation energy. Hence, more particles will have energy greater than activation energy.”
Miracle Learning Centre hope you have understood the speed of reaction and how it helps you to answer chemistry tuition questions. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about speed of reaction and chemistry.
There is an age-old myth about Chemistry among the students which is that students only believe that this subject is a very bland and boring subject which is only a combination of various formulas and principles which are extremely complex and difficult to memorize. They learn Chemistry only because this subject is mandatory for the various future scopes of higher study and professions. Very few students actually love to read Chemistry and move ahead with it. Miracle Learning Centre was established with only one goal which is to make Chemistry easy and fun for every student. We believe that every student can achieve excellence if they are taught in the correct way and for this we have introduced the most innovative course of A level chemistry tuition, O level chemistry tuition, JC chemistry tuition in Singapore where we always implement fun and exciting techniques like illustrations, presentations, models, games, etc so that our students never feel bored and instead be able to increase their marks gradually.
