Rate laws and Stoichiometry
● Homojen reaksiyon Sadece tek faz içerir. ● Heterojen reaksiyon Birden fazla faz içerir.(Reaksiyon genel olarak iki fazın arayüzeyinde veya yakınında olur.) Tersinir (Reversible) reaksiyon reaktantların veya ürünlerin konsantrasyonlarının onların denge konsantrasyonlarına göre miktarlarına bağlı olarak her iki yönde de reaksiyona girebilirler. Tersinmez (Irreversible) reaksiyon sadece tek yönde ilerleyen ve reaktantlar bitene kadar kadar aynı yönde süren reaksiyonlardır. Bir tersinmez reaksiyon hiç denge durumu yokmuş gibi devam eder. Hiçbir reaksiyon kelimenin tam anlamıyla tersinmez değildir.Ancak birçok durumda denge o kadar üründen yanadır ki ters reaksiyon ihmal edilebilir. …

Solution Stoichiometry
SOLUTION STOICHIOMETRY – Previously, we dealt with comparing components of a chemical reaction by converting mass of substances to moles. – Now we will consider solutions where we will need to convert volumes to moles to make comparisons. GRAVIMETRIC ANALYSIS Measure the concentration of solution by measuring the mass of a precipitate formed. – Use grams of precipitate to find moles of solute. – Divide by volume of solution to find concentration. VOLUMETRIC ANALYSIS Measure the concentration of solution by measuring the volume of solution need to find stoichiometric equivalence between reactants using a…

Stoichiometry of Chemical Formulas and Reactions
Stoichiometry of Chemical Formulas and Reactions The law of definite proportions states that the element ratios for a given compound remain constant. The subscripts in a chemical formula may therefore be used to define molar ratios between the elements in the formula or between an element and the compound. For example, the chemical formula for water is H2O. Therefore, we can write …

Stoichiometry Review Practice
1. Explain the term mole ratio in your own words. When would you use this term? 2. Carbon disulfide is an important industrial solvent. It is prepared by the unbalanced reaction of carbon with sulfur dioxide. C (s) + SO2 (g) –> CS2 (l) + CO (g) a. How many moles of carbon disulfide form when 2.7 moles of carbon react? b. How many moles of carbon are needed to reaction with 5.44 moles of sulfur dioxide? c. How many moles of carbon monoxide form at the same time 0.246…

Stoichiometry Summary
Solution Terminology The solute is the substance that is present in the smaller amount. The solvent is the substance that is present in the larger amount. Either may be a solid, liquid or gas although some solute/solution combinations are more common. A concentrated solution has a relatively large quantity of s specific solute per unit amount of solution, a dilute solution has a relatively small quantity of the same solute per unit ammount of solution. Solubility is a measure of how much solute will dissolve in a given amount of solvent and a…
