investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must control

affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to the Collision Theory‚ during a reaction‚ particles

Determining Order from Rates of Reactions AP Chemistry Purpose The focus of this experiment is to recognize that when aqueous solutions of potassium iodate ion (KIO3-) and bisulfite ion (HSO3-) are mixed‚ a series of reactions will occur‚ and the final reaction is signaled by the appearance of a dark blue color. My partners and I investigate how the concentration of the reactants affects the rate of reaction. The purpose of this lab is to find

Size‚ Temperature‚ Concentration‚ and a Catalyst on Reaction Rate Introduction: Chemical reactions can be affected by a number of different factors. Particle size‚ temperature‚ concentration of a solution‚ and catalysts play a big role in the rate of reaction‚ they determine how fast a reaction will occur. According to the collision theory‚ the rate of reaction depends on the frequency of effective collisions between particles. Every reaction is different in that they all require different conditions

Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries

purpose of laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures were prepared in separate

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

Purpose: To determine the effect of various factors on the rate of reaction between an enzyme andits substrate‚ and also to determine the optimal ranges under which the enzyme activity ismaximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme willincrease until it reaches optimum pH range (pH 7) because the enzyme is less denaturedwhen it reaches the preferred pH level
