What is the relation between reaction time and radius of the unreacted core when chemical reaction controls?
When a chemical reaction controls the rate of reaction, the reaction time is often inversely related to the radius of the unreacted core. As the radius increases, the volume of unreacted material grows, leading to longer diffusion paths for reactants to reach the core. Consequently, larger unreacted cores result in slower overall reaction rates and longer reaction times. This relationship is critical in understanding reaction kinetics, particularly in heterogeneous reactions involving solid reactants.
Is chemical reaction alive?
No. A chemical reaction is not alive.
How can the efficiency of a chemical reaction be expressed?
A chemical reaction is represented by a chemical equation.
What is a process that changes one or more new substances?
A chemical reaction is a process that changes one or more substances into new substances with different chemical properties. This involves the breaking and formation of chemical bonds between atoms or molecules.
If you say 'oxygen gas supports combustion' are you talking about a chemical or physical reaction?
Combustion is a hemical reaction.
What is a chemical change also referred to as?
Chemical reaction
How does an engine have a chemical reaction?
Combustion is a chemical reaction.
Is chemical reaction alive?
No. A chemical reaction is not alive.
What chemical is formed in a chemical reaction?
A new chemical substance is formed during a chemical reaction by rearranging the atoms of the reactants. The products of a chemical reaction have different properties compared to the original reactants.
What is the characteristic of chemical equation?
A chemical reaction is a graphical representation of a chemical reaction.
How can the efficiency of a chemical reaction be expressed?
A chemical reaction is represented by a chemical equation.
What is critical charge?
"Critical charge" typically refers to the minimum amount of energy required to trigger a specific reaction or process. In chemistry, this can relate to the activation energy needed for a chemical reaction to occur. In electronics, it may refer to the threshold voltage required to induce conduction in a semiconductor device.
A chemical reaction can be concisely represented by a chemical what?
A chemical reaction can be represented by a chemical equation.
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.
What is cheamical reaction?
a chemical reaction is a reaction were the two chemicals change into a new chemical.
