Kinetics of the Harcourt-Essen Reaction Name: Manpreet Kaur Candidate Number: 7123 AS and A2 Aims: AS AIMS: 1. Investigate the effect of temperature on the rate of reaction. For this aim 3 sets of results will be obtained by timing how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2.

MANUFACTURE OF SULPHURIC ACID IN INDUSTRY 1. Contact process produces more than 90% of the world’s sulphuric acid. 2. The raw materials used for the manufacture of sulphuric aced are sulphur‚ air and water. 3. The Contact process consists of three stages. a) Production of suphur dioxide b) Conversion of sulphur dioxide to sulphur trioxide. c) Production fo sulphuric acid 4. Stage I: Production of sulphur dioxide a) Sulphur is burnt in air to produce sulphur dioxide. S(s) + O2 (g)→SO (g) b) Burning

Introduction Comprehensive Agrarian Reform Program (CARP) In 1988‚ the government launched the CARP through Republic Act (RA) 6657‚ seeking the distribution of some 10M hectares of agricultural lands to farmers and regular farm workers. The government also directed specific agencies to provide the required support services and other factors needed to ensure socio-economic upliftment of the lives of the beneficiaries through Executive Order (EO) No. 229. The DTI’s participation in the CARP was

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus
