In a closed system, any reversible reaction will eventually reach a dynamic balance between the forward and reverse reactions. A system is said to reach chemical equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. At this point, no further changes will be observed in the amounts of either the reactants or products. Chemical equilibrium can be further defined, therefore, as the state where the concentrations of reactants and products remain constant with time. This does not mean the concentration of reactants and products are equal. The forward and reverse reactions create an equal balance of opposing rates.…
When we bake/cook something, we use a specific amount of each ingredient. Imagine if you made a batch of cookies and used way too many eggs, or not enough sugar. YUCK! In chemistry, reactions proceed with very specific recipes. The study of these recipes is stoichiometry. When the reactants are present in the correct amounts, the reaction will produce products. What happens if there are more or less of some of the reactants present?…
After a reaction has occurred for awhile at a given temperature, the forward and reverse reaction rate will eventually be equal. Although you may get this confused, the concentration may not be equal, but the rate will. This occurs in a closed system. In other terms, dynamic equilibrium is when no change appears; as the rate of reverse and forward are equal. The relationship between reactants and products is portrayed in this property. For example; imagine there are 100 people at a party. Every ten minutes, 5 people leave; however coincidently 5 people arrive at the same time. The amount of…
In a chemical reaction, the amount of starting material for a chemical reaction limits the amount of product that can be formed.1 The principle of limiting reactants relates to this lab because the limiting reactant is the substance that is used up first in a chemical reaction. The amount of product was limited by that reagent. The excess reactants were considered to be the other reagents that were presented in excess of the quantity that was reacted with the limiting reagent. The theoretical yield was determined as the amount of product obtained when the limiting reagent was completely used. The limiting reagent was identified in order to calculate the percent yield of the reaction.…

Some chemical reactions involve random amounts of reactants. The reaction will stop when one or more of the reactants run out. (limiting)…

In an equilibrium reaction, the ratio of the products to the reactants is a constant.…
Chemical reaction,is the process by which one or more substances are converted into one or more different substances.Old bonds break and new bonds form. The original substances are called reactants. The resulting substances are called products. It is a simple chemical reaction. Another simple reaction might involve a reactant molecule breaking apart. Many enduring substances such as rock and water are highly stable. One molecule of methane and two molecules of oxygen yield one molecule of carbon dioxide. Chemists summarize chemical reactions using formulas called chemical equations. Chemical equations generally show the product formed when the…
Chemical reactions occur when two or more molecules interact with each other, but that can only occur when they interact at a specific geometrical orientation and when the activation energy needed for the reaction is exceeded. The reactions can either be endothermic, with heat being absorbed from the surroundings to the system, or endothermic, with heat given…
Chemical equations are the symbolic representations of chemical reactions that are made up of reactants and products. It is made up of the chemical formulas of the reactants and the chemical formula of the products. The reactants are the substances or chemicals that takes part in during a reaction and the products are the chemicals are the substances that result from the chemical reaction. Reactants are on the left side of the chemical equation and the products are on the right side of the chemical equation. They are both separated by an arrow, that simply means “yield”. This arrow has the general purpose to show action between the products and the reactants. It is also supposed to represent a net forward reaction, meaning there is a complete…
