The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.
What else can I help you with?
When after a chemical reaction do the reactants still exist?
There can be many cases. One of them being that you take the reactants in excess then a little portion of the reactants remain. Another is the reaction cannot take place. In reversible reactions. But you should note that the exact proportion of reaction cannot remain in a reaction cause you are trying to form new comounds during this reaction.
In a reverse reactionproducts are formed from reactants and reactants are formed from products When they yield the same amount?
This indicates that the reaction has reached equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, but both are still present in the system.
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
What factor in reaction rate is related to the amount of reactants?
This is the concentration of reactants.
Is defined as the number of atoms molecules or ions that react in a specific amount of time to produce products?
This is known as the reaction rate, which quantifies the speed at which reactants are consumed or products are formed in a chemical reaction. It is typically expressed in terms of moles of reactants consumed or products formed per unit time. Factors such as temperature, concentration, and catalysts can influence the reaction rate.
Why the amount of reactants and product change in a reversible reaction?
The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.
Why the amounts of reactants and products do not change in a reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
Why amount of reactant and product do not change in reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
Why the reversible reaction do not go to completion?
Reversible reactions do not go to completion because the reactants are constantly converting into products and vice versa. At equilibrium, the rates of the forward and reverse reactions are equal, resulting in a dynamic state where both reactions continue to occur but at an equal pace. As a result, there will always be some amount of reactants and products present in a reversible reaction system.
When does a chemical reaction reaches equilibrium?
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants
What happens to the mass of reactants in a chemical reaction?
The reactants will form products, so the amount of reactants will decrease, proportionally to the increase in products. The amount can be expressed in mass, concentration or moles.
What happens to the amounts of reactant and products after a reaction has reached chemical equilibrium?
The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.
How are chemical equations useful?
Chemical equations show the reactants and products involved in a chemical reaction and provide important information about the stoichiometry of the reaction, including the mole ratios of reactants and products. They also help predict the products of a reaction and quantify the amount of reactants needed or products formed.
What does the percent yield of a reaction measure?
It measures the amount of reactants actually produced in a reaction compared to the amount that would theoretically be produced if 100% of the reactants were converted to products according to the stoichiometry of the reaction. It is found by: actual moles of products ÷ predicted moles of products * 100%
What does a stoichiometry graph reveal about the relationship between reactants and products in a chemical reaction?
A stoichiometry graph shows the quantitative relationship between reactants and products in a chemical reaction. It reveals the ratio in which reactants combine to form products, providing information on the amount of each substance involved in the reaction.
When after a chemical reaction do the reactants still exist?
There can be many cases. One of them being that you take the reactants in excess then a little portion of the reactants remain. Another is the reaction cannot take place. In reversible reactions. But you should note that the exact proportion of reaction cannot remain in a reaction cause you are trying to form new comounds during this reaction.
What would happen to the amount of products if you increase the amount of one of the reactants?
Increasing the amount of one reactant typically increases the amount of products produced until the reactant is used up. Once the reactant is exhausted, the reaction will reach equilibrium and the amount of products will no longer increase.
