Is it important for the concentration of the reactant solutions to be equal?
Yes. The volume you have of a particular solution does not have anything to do with the concentration of that solution.
What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
When the concentration of the reactant is decreased, the rate of chemical reaction go slow.
The equilibruim constant is the ratio of product concentration to reactant concentration at equilibruim A reaction will likely go to completion if the equilibrium constant?
a} Is very high.
What is a decomposed reaction?
It is a reaction that has only one reactant and multiple products. Meaning one chemical decomposes/splits to form others. H2O2 > H2 + O2.
How does an equilibrium reaction respond to the addiof extra reactant?
The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease. (If there were no available unadded reactant, the reaction would not technically have been in equilibrium at the start, even though it may have reached a steady state that can persist for a long time in the absence of changed conditions.)
What is the definition of a reactant concentration?
Reactant concentration is the exponent or index in which a substance's concentration term is increased in the rate equation. Reactant concentration is also known as the order of reaction.
In the chemical reaction in which sucrose is heated and decomposes to form carbon dioxide and water is a reactant?
Yes, sucrose is the reactant.
If you double a concentration of a reactant then the rate of the reaction doubled The order with respect to the reactant is?
First order; the rate is directly proportional to the concentration of reactant.
What is the reactant when sucrose is heated and decomposes to form carbon dioxide and water?
Sucrose
Did a chemical reaction take place if a reactant is smaller?
Yes. If Concentration of a reactant has decreased, that means that that concentration was used in the formation of a product.
Is it important for the concentration of the reactant solutions to be equal?
Yes. The volume you have of a particular solution does not have anything to do with the concentration of that solution.
How the limiting reactant control the product?
The yield of the reaction depends in this case only on the concentration of the limiting reactant.
What happens to the yield of ammonia when the concentration of reactant is increased?
..
The speed at which a reactant will change to a product is proportional to its?
molecular concentration
What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
When the concentration of the reactant is decreased, the rate of chemical reaction go slow.
What are 4 ways the rates of chemical reactions can vary?
Chemical reactions proceed via the formula: R=k[a]x [b]y/[ab]c Where R= reaction rate k= constant [a] = concentration of first reactant [b]= concentration of second reactant [ab]= concentration of product x,y,c = exponential that are unique to every reaction. R therefore varies by: Concentration of reactant a Concentration of reactant b Concentration of product ab Value of reaction constant k Reaction rate can also be affected by temperature but that's an entirely different equation. The Arrhenius equation.
Is water a reactant to heated and decomposes to from carbon dioxide?
No. Water is H2O. It doesn't have carbon and hence will never form carbon dioxide.
