Aim: This experiment will aim to show how the amount of substrate affects the rate of the reaction. Hypothesis: In this experiment I think the amount of substrate will simply increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled

Infra-Red Spectroscopy of HCl and DCl gas Abstract Fourier-transform infrared spectroscopy has been very useful in helping scientists examining molecules of HCl and DCl. Because deuterium has a greater mass than hydrogen‚ the IR band shown for HCl is at a higher wavelength than DCl. The absorption of light in DCl was at lower frequency 1700-2200 cm-1 because D is bigger and heavier. That’s why the vibrations on the IR were shorter for DCl compared to HCl. The stretching of HCl on the IR region was

makes them highly specific and only work on one or a few similar chemical reactions. Enzymes themselves are not consumed in the reaction‚ but they help attract substrates into correct position to undergo chemical reaction. Enzymes greatly speed up the rate of biological reactions by lowering the energy of activation. To get a sense of the speed and efficiency of enzymes‚ substrates can be transformed to products at the rate of thousands of times per second with the enzymes. If we consider the total

Affecting Rates of Chemical Reactions Prepared By: Kelly Gunter For: Ms. Brohman Course: SCH-4U Introduction The main purpose of this lab was to investigate how temperature‚ concentration‚ the addition of catalysts‚ and the substitution of a more reactive reactant‚ can affect the reaction. The collision theory explains that in order for a reaction to occur‚ reacting particles must collide with one another. An effective collision makes reactants result in a reaction and for to

Investigating Factors that Affect the Rate of Reaction of the Decomposition of Hydrogen Peroxide Emilio Lanza Introduction- In this experiment‚ the rate of reaction‚ calculated in kPa sec-1‚ of the decomposition of hydrogen peroxide will be investigated to see how the change in concentration of hydrogen peroxide and the change in temperature affect the rate of reaction. The data will be collected by measuring the gas pressure. The product of Hydrogen Peroxide is oxygen in a gas state thus

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation

Reminder: These notes are meant to supplement‚ not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction
