the rate of decomposition of hydrogen peroxide.” Chemical equilibrium is the state of constant composition attained when opposing reaction rates become equal. There is an essential relationship between reaction rates and chemical equilibrium‚ one that we can describe quantitatively. At first thought‚ the connection may seem obscure - do we not need to be far from equilibrium to properly measure reaction rates? The dynamic nature of chemical equilibrium means that both forward and reverse reactions

Mass relationships in a chemical reaction Introduction: The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words‚ the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction‚ the total mass will be the same at any point in time in any closed system. http://www.nature

Total continuity equation is the principle of the conservation of mass when applied to a dynamic system. The unit of this equation is mass per time. In overall balance‚ only one TCE can be written. CCE is based on component balance. Unlike mass‚ chemical components are not conserved. If reactions occur on a system‚ the number of moles of an individual component will increase if it is a product and will decrease if it is a reactant. The unit of CCE is moles of component per unit time. While EE‚ the

For our second lab in Sports nutrition‚ we made pizza! For this‚ we only used one recipe for making the crust‚ which the only thing we needed to add was water and some oil. I really enjoy making homemade pizza sauce and homemade crust at home. The first thing we had to do was figure out our toppings. I suggested banana peppers‚ no one in my group had ever tried them before so they weren’t sure. Mrs. Conway got the ingredients we requested so the next day we made up our pizza crust which consisted

Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate
