Abstract: In the course of this experiment the rate of isomerism for the coordination complex cis[Co(en)2Cl2]Cl was determined using UV/Vis spectrometry. Using a range of wavelengths the optimum spectrometer setting for analysis was identified. The corresponding maximum and minimum absorbance of the cis and trans isomers respectively at 540 nm meant that it was selected as the wavelength to determine the rate of conversion between the isomers. The first order rate constant was calculated to be 0.0092 m-1

Some 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

Topic: The effects on China’s economy due to fluctuation of exchange rate. 1. Introduction China’s economy is huge and expanding rapidly. In the last 30 years‚ the rate of Chinese economic growth has been almost miraculous‚ averaging 8 percent growth in Gross Domestic Product (GDP) per annum. The economy has grown more than 10 times during that period‚ with Chinese GDP reaching 3.42 trillion US dollars in 2007. China already has the biggest economy after the United States and most analysts

Factors Influencing Rate of Reaction Aim To investigate several effects believed to influence rate of reaction‚ concentration of a substance and temperature‚ and observe the effects. Hypothesis Concentration and temperature will both increase the rate of reaction in accordance with collision theory. Introduction The reaction rate or rate of reaction for a reactant or product in any given reaction can be defined as the speed with which a reaction occurs. For example‚ the oxidation of iron

To manage exchange rate risk activity‚ Tiffany’s objectives should be to minimize foreign exchange rate risk and lower counterparty risks. We want to minimize these risks because Tiffany & Co. is selling goods that are denominated in US dollars‚ but sold for yen in the Japanese market. The objective of this program is to prevent the depreciation of the yen against the US dollar by hedging the currency. The expected Japanese sales of Tiffany & Co. should be actively managed by purchasing hedging contracts

certain factors of a chemical reaction affect the rate of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction‚ because when the temperature

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will
