What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
Rate of reactions?
The rate of a reaction is the time it takes for a reaction to take place. The rate of reactions can be affect by different factors such as the temperature, the air pressure, the concentration of each substance and whether a catalyst is used (a catalyst is something that lowers something's activation energy so the reactants have more energy to react). A reaction happens when atoms collide with each with a big enough force therefore a bigger surface area would help speed this up. Also the amount of energy the particle/atoms have helps. With these factors you can determine the speed at which a reation happens. Any questions?
Why does forward reaction is decrease in rate as time increase?
This is because the reactants are being used up to make products. Unless you add more reactants to the solution, the rate at which products will be made will start to diminish until there is an equilibrium. At this point products will be converted to reactants and reactants will be converted to products and the equilibrium will not shift however the forward rxn and the reverse rxn will be occurring at the same rate
How is a catalyst different from the reactants and products of a chemical reaction?
A catalyst is not consumed in a chemical reaction, unlike reactants that are consumed to form products. Catalysts lower the activation energy required for a reaction to occur, increasing the reaction rate without being permanently changed or used up in the process. Reactants are the starting materials that undergo a chemical reaction to form products, which are the final substances produced at the end of the reaction.
How is the rate of reaction compared with the time the reaction is carried out?
The time it takes for a reaction to occur is a function of the reaction rate constant and the amount of reactants. However, how long it takes for a reaction of occur completely depends on the type of reaction it is -- what the order of the reaction is. A first or second order reaction reaction will occur much faster earlier on, but slows down significantly once the reactants are depleted. The rate of a zero order reaction is constants regardless of the concentration of the reactants.
What happens to the reaction rate as the reactants get used up in the reaction?
The rate of the reaction begins to decrease as reactants are used up (apex)
What happens to the rate of reaction as the reaction progresses?
The rate decreases as reactants are used up.
What happens to the reaction rate as the reactions get used up in a reaction?
The rate of the reaction begins to decrease as reactants are used up (apex)
What does the rate law used to determine the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
What effects does the concentration of reactants have on the rate of the reaction?
increasing the concentration increases the rate of the reaction
What is a change that affects chemical reaction rate?
Factors affecting the reaction rate:- Concentrations of the reactants- Temperature- Pressure- Sirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
Products and reactants are used and created at the same rate when a reaction is at this stage?
Chemical Equilibrium
How is a reaction rate measured experimentally?
There are two ways people can measure the rate of reaction. People can measure how quickly the reactants are used up as they react to make products. Or people can measure the rate at which the products of the reaction are made.
What does the rate law used to determine the rate of reaction?
the person before me was a idiot/S.O.B here you go: The rate of a reaction is calculated using the concentrations of reactants. your welcome ^_^ follow me on instagram = santana_love_
