Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different

Experiment A1: Kinetics of the Reaction between Acetone and Iodine The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained. The stoichiometric equation for the reaction between iodine and acetone is below‚ followed by the rate equation (where x‚y‚z and k are the values to be obtained): I2 + CH3COCH3 CH3COCH2I + HI -d[I2]/dt = k [I2]x [CH3COCH3]y [H+]z

relations could be determined. Experimental results‚ which indicated an electronic influence on the regioselectivity‚ could be confirmed and appear to be predictable. The reaction follows a [3þ2] mechanism. We additionally report results on the experimentally observed competing dihydroxylation reaction and the ligand-induced reaction rate acceleration. Introduction Sharpless et al. reported in the 1970s an aza-analogon of the osmium-catalyzed cis-vicinal dihydroxylation (DH)1 of alkenes‚ the

on the Rate of Reaction? By : 22/10/2013 The effect of changing the surface area on the rate of reaction? Unit Question: Should we speed things up or slow them down? Hypothesis: According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area increases the rate of reaction increases.

Chemical Engineering In the future I would like to become a chemical engineer. I really enjoy chemistry and hands on work “Chemical engineering is the application of chemistry to large scale industrial systems.” (Chemical engineering). I enjoy helping build different things like skateboards‚ ramps and‚ fixing parts on different things. When I took the sixteen personality quiz it said I was a virtuoso. The virtuoso likes hands on work and exploring ideas which I think fits my personality perfectly

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to

Chemical Engineer The chemical engineer is an invaluable link between scientific principles and manufacturing realities. It involves the use of chemical‚ physical‚ and engineering principles. The scientist in a laboratory does basic research to develop new compounds and processes. When the scientist discovers a product that may be useful‚ the chemical engineer takes over. They adapt the product for big scale manufacturing. They do this by designing a plant to produce the item on large scale
