A catalyst increases the rates of chemical reactions by decreasing the activation energy or energy barrier which either delays or prevents a reaction occurring. When the activation energy is high, reactions delay occurring because.it takes a lot of frequency of collisions to equal or overcome the activation energy. Studying and monitoring how fast or slow…
A reaction could occur very fast or very slowly depending on a lot of factors like temperature, pressure, concentration etc. It is pertinent to understand the basic chemistry of Chemical Kinetics Rate of reaction is defined as the amount of reactants converted to products per unit time.During a chemical reaction, the amount of reactants decreases…
Electrochemistry is the branch of chemistry that deals with the gain or loss of electrons during chemical reactions. In electrochemistry, we talk about electrolytic cells and eletrochemical cells. It is pertinent to mention that electrochemical cells convert chemical energy to electrical energy while electrolytic cells convert electrical energy to chemical energy. I will start by explaining…
In Chemistry, the equilibrium position of a reaction can be shifted either to the right or left in order to get the maximum yield of reaction. An equilibrium is a state in a reaction when the rate of forward reaction equals the rate of backward reaction in such a way that there is no net…
Alkenes and alkynes are called unsaturated compounds basically for two major reasons Additionally, they both burn with more smoky flame due to their unsaturation. What is an unsaturated compound? An unsaturated compound is a compound that has double or multiple bonds.Alkenes and alkynes are called unsaturated, and they participate in some basic reactions. Although I…
One of the questions you will encounter as a chemistry tutor is on why distilled water is used in the laboratory, so i thought i should share from my more than a decade of teaching Chemistry the basic uses of distilled water. In performing experiments in chemistry, there is a need to use water that…
Air can be polluted and some basic pollutants that we usually discuss in IGCSE chemistry that we need to discuss. What are the constituents of air? Air is a mixture just like other mixtures like alloys(brass, bronze), blood it has constituents not chemically bound together., The constituents of a and the percentage composition Constituents of…
There are various Common Glassware and Equipment in the chemistry laboratory The glassware and pieces of equipment used in the chemistry laboratory are actually many but they have specific uses. This is a complete list of piecces of apparattus used in chemistry to demostrate titration For example, the delivery tube is used to bubble gases…
What is quantum chemistry? Quantum chemistry is the branch of theoretical chemistry that applies quantum mechanics to study the behavior and properties of sub-particles of an atom, especially the electron. What is an orbital? An orbital is a region where there is a high probability of finding an electron. There are basic principles that determine…
How do you identify a gas? Identifying a gas involves a lot of steps though there is a basic chemical test for each gas which we will cover in this article. However, we can suspect the presence of gas by some basic physical properties though it won’t be conclusive. This is because some gases have…
