Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

What Happens When the Supply Curve Shifts Student Feb 17‚ 2013 Principles of Microeconomics The Supply Curve: Price is usually a major factor in the quantity supplied to the market. For a particular good with all other factors held constant a table could be constructed of price and quantity supplied based on observed data. This table is called a supply schedule‚ example: Supply Schedule Price Quantity Supplied 1 12 2 28 3 42 4 52 5 60 By graphing this data the

Enzyme concentrations Hypothesis The higher the concentration of protease enzyme the higher the rate of breakdown of the egg white. This is because egg white is mainly formed of collagen‚ which is a protein‚ which is what the enzyme protease breaks down. The more enzyme there is the more enzyme substrate complexes are formed which break down peptide links between the monomers of the protein accelerating the amount of protein broken down in a space of time. How the results will be obtained

What would happen nowadays without cars? How would it be to use everyone public transport? Cars are the answer to our needs to be independent of each other and to travel freely wherever we want. History The cornerstone of the BMW empire dates back to 1916 in Munich‚ when Franz-Josef Popp and Max Friz set up Bayerische Flugzeug-Werke (Bavarian Aircraft Industry) on March 7th. Thus‚ contrary to expectations‚ the beginnings of BMW consisted of the production of aircraft engines‚ not cars. Two years

Factors that Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * nature of reactants - particle size * temperature * catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for

relates to what is being studied by showing how random error can effect and experiment. This experiment teaches the students how to determine density‚ volume‚ and percentage errors. OBJECTIVE The objective of this experiment is to determine the order with respect to permanganate ion and to oxalic acid concentration for the reaction of potassium permanganate and oxalic acid solutions. Other goals include‚ writing a rate equation and determining the effect of increased temperature on the rate of this

What Happens in Narnia Does not Stay in Narnia We have all heard phrase‚ “What happens in the jungle stays in the jungle‚” or some variation of it. It can be a good way to dodge questions about your trip‚ or a quick way to tell people what happened without actually telling them what happened. It is common to hear this phrase in movies‚ and sometimes you may read it in a book. Many times this is a fun way to end a story‚ it leaves mystery. But what would happen if we actually talked

Initial Capital Investment Before investing any amount of capital into a business‚ organisation or idea‚ It is crucial that research is conducted into the market and the market share of the business. From this‚ an estimation can be gained if it is a wise idea and what the possible return maybe. The initial capital investment must be sufficient to cover all costs of the setting up‚ opening and running of the business until the business is making enough income from sales and services to aide or

larger enzyme molecule. Moreover‚ the molecule that the enzyme acts upon (substrate) fits precisely into the depression and forms an enzyme-substrate complex. The substrate molecule is held into the active site by bonds that temporarily form between certain amino acids of the active site and groups on the substrate molecule. Enzyme-substrate complex: The enzyme-substrate complex formed when the enzyme binds with its substrate lowers the activation energy (minimum amount of energy needed to activate
