Interesting facts about rates of reaction

The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate. Some reactions take hundreds, maybe even thousands, of years while others can happen in less than one second. In a Decomposition Reaction, one reactant breaks down into two or more products. These types of reactions are usually endothermic or require a catalyst to speed up their progress. An example is Hydrogen Peroxide (H2O2) decomposing into Water and Oxygen (O2). The general form for a decomposition reaction is AB -> A + B.

The reaction is the mirror image of photosynthesis: glucose + oxygen yields carbon dioxide + water. Like all living things, plants go through cellular respiration to obtain energy for growth and reproduction. If you increase the temperature in the experiment the rate of the reaction increases for example, for many reactions happening at room temperature, the rate of reaction doubles for every 10 degrees rise in temperature, this means the rate can be quadrupled if the temperature is raised by 20 degrees. The rate of a reaction is defined in terms of the rates with which the products are formed and the reactants (the reacting substances) are consumed. For chemical systems it is usual to deal with the concentrations of substances, which is defined as the amount of substance per unit volume. The immune response, called an allergic reaction, occurs because the immune system attacks proteins in the food that are normally harmless. The proteins that trigger the reaction are called allergens. The symptoms of an allergic reaction to food can range from mild (itchy mouth, a few hives) to severe (throat tightening, difficulty breathing). The mean rate of reaction can be calculated using either of these two equations: Measuring mass The change in mass of a reactant or product can be followed during a reaction. Some reactions take place at a very fast rate. For example, combustion of LPG in kitchens is a femto chemical reaction because it takes place at a very fast rate. These chemical reactions can take place in 10 -15 seconds. So, the study of such chemical reactions which take place in 10 -15 seconds is called femto chemical kinetics.

Sept. 26: Bank of England raises rate to protect gold standard. Oct. 24: Black Thursday, panicked sellers trade almost 13 million shares on NY Stock Exchange (3x normal volume then); investors lose $5 billion. Oct  23 Feb 2012 The rate of reaction was discussed in terms of three factors: collision frequency, the collision energy, and the geometric orientation. The chemical test used to identify a gas as oxygen relies on the fact that increasing the concentration of a reactant increases reaction rate. It is important to emphasize that a catalyst is a substance that speeds up the rate of the reaction but is itself not  The reaction is called a clock reaction because the amount of time that elapses before the solution turns blue depends on the concentrations of the starting chemicals. In this chemistry project, you will explore factors that affect the rate of the  It is often more convenient to assume the reaction is "going" at a somewhat constant rate and think of the x axis simply as time. You will also use the all- important fact that [E] = [Eo] – [ES], where Eo is the initial amount of enzyme. Note that  Diet Coke and Mentos: What is really behind this physical reaction?

Reaction rate, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in
