What is an example of a slow reaction?
Rusting of Iron Formation of crude oil by a geochemical reaction and disintegration of radium are other examples of slow reactions.
What is an example of a chemical reaction that occurs at a very slow rate?
In general the reactions between covalent compounds are slow. For example rusting of iron or fermentation of sugar into ethyl alcohol and carbon dioxide can take place in several hours or even in several days. In the same way weathering of rocks takes place in millions of years.
Why are some reactions slow?
Reactions usually slow down as time goes on because of the depletion of the reactants. The rate constant, or the specific rate constant, is the proportionality constant in the equation that expresses the relationship between the rate of a chemical reaction and the concentrations of the reacting substances.
What are slow changes?
The changes which take place in a long period of time are called slow changes whereas, the changes which take place in a short period of time are called fast changes. Examples: (a) Rusting of iron, ripening of fruits, growing of trees are slow changes.
How do you know if a reaction is fast or slow?
The reaction mechanism is the step-by-step process by which reactants actually become products. The overall reaction rate depends almost entirely on the rate of the slowest step. If the first step is the slowest, and the entire reaction must wait for it, then it is the rate-determining step.
Why does rate of reaction slow?
Reactions usually slow down as time goes on because of the depletion of the reactants. In some cases the addition of a substance that is not itself a reactant, called a catalyst, accelerates a reaction.
What is an example of a very slow chemical reaction?
, Chemistry major The rusting of iron, the fermentation of sugar into alcohol, the chemical weathering of rocks, and the photosynthesis process in plants are slow chemical reactions. One of the most example is formation of rust When iron (Fe) reacts with the atmospheric water and Oxygen, it produces rust .
What are some slow chemical reactions in everyday life?
Photosynthesis
What is the slowest chemical reaction?
Slow Chemical Reactions: There are chemical reactions that are fast, but there are few that are slow and take place naturally and in the course of time the difference is notable. Few of the examples of slow chemical reactions are: 1) Photosynthesis. 2) Rusting of iron . 3) Rock formation. Photosynthesis
What makes a chemical reaction go slower?
There are several factors that affect the speed of a reaction: Nature of the reactants Particle size of the reactants Concentration of the reactants Pressure of gaseous reactants Temperature Catalysts
