Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

The SN2 reaction requires three qualities: a strong nucleophile‚ a good‚ unhindered leaving group‚ and a polar‚ aprotic solvent. For our reaction‚ we have all three bases covered. The nucleophile is an alkoxide‚ a deprotonated alcohol. Technically‚ because our alcohol is a phenol‚ the conjugate base is called a phenoxide. Phenol itself has a pKa of about 10‚ but our alcohol has more resonance opportunities‚ so the pKa is down around 8. This is sufficiently acidic for use of weak base like K2CO3 for

Basic Estimation Techniques In order to implement the various techniques discussed in this class‚ the students must be able to determine the mathematical relation between the economic variables that make up the various functions used in economicsdemand functions‚ production functions‚ cost functions‚ and others. For example‚ a manager often must determine the total cost of producing various levels of output. As you will see later‚ the relation between total cost (C) and quantity

Peter Gillen (1) a one-paragraph summary of the case setting/background The case is set in the auto parts supply industry. Automek is a supplier to Ford‚ the OEM in this case. Agile Electric‚ located in southern India‚ is a supplier to Automek. Automek has invested significant time and resources into the development of Agile due to its low cost of manufacturing capabilities. Agile has been asked to manufacture an actuator assembly for Automek. Agile is concerned about their ability
