Why crushing is done for a reactant before a chemical reaction?
the surface area of the particles are incresed so that the chemical reaction takes place fastly. for example if u have a granular sugar or powdered sugar what will be solved in water fastly surely the powdered form . bcoz of crushing surface area increses ! [ ENGR RIZI NFC IET MULTAN]
How can you identify the prduct as being different from the reactant?
A product is identified as different from the reactant by analyzing the chemical structure, physical properties, and any changes in composition that occur during a chemical reaction. This can be done through techniques like spectroscopy, chromatography, or elemental analysis to determine the presence of new substances formed after the reaction.
What happens If you decrease rate of chemical reaction?
Decreasing the rate of a chemical reaction would slow down the speed at which reactants are converted into products. This can be done by lowering temperature, decreasing reactant concentration, or adding inhibitors. Ultimately, the reaction will take longer to reach completion.
What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
The speed of a chemical reaction can be increased by increasing the temperature, as higher temperatures provide more kinetic energy to the reactant molecules, leading to more frequent and energetic collisions. Another way is to increase the concentration of the reactants, as a higher concentration provides more reactant particles in a given volume, increasing the likelihood of collisions and reactions.
How does surface area affect the rate of reaction?
The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. If the surface area of a reactant is increased: More particles are exposed to the other reactant, there are more collisions, the rate of reaction increases.
What is mean by physio-chemical reaction?
when the reaction done between solid and liquid interface is called physio-chemical reaction.
The substances present when a chemical reaction begins?
The substances that are present when a chemical reaction begins are reactants, at the end of the reaction they form products.
What things can be done to change how fast a chemical reaction occurs?
You can add a catalyst, or raise the temperature, or change the pressure, these are some of the things done to speed up a chemical reaction.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
How can one predict the products of a chemical reaction?
To predict the products of a chemical reaction, one must understand the reactants involved and their chemical properties. This can be done by applying knowledge of chemical bonding, reaction types, and balancing chemical equations. Additionally, using tools such as the periodic table and reaction mechanisms can help in making accurate predictions.
What is an in situ reaction?
An in situ reaction refers to a chemical reaction that takes place in the same location where the reactants are initially present, without removing them from that environment. This technique is commonly used in various applications such as environmental remediation, material synthesis, and biological studies to observe reactions in their natural settings.
What do you call a chemical reaction made by mixing two different compounds?
A chemical reaction made by mixing two different compounds is also known as chemical synthesis. This is done to obtain a product or several products.
