Unformatted text preview: The phenol concentration and versus time data was plotted in as shown below. a) What is the reaction order? First b) What is the value of the reaction rate? -0.0499 Units hr-1 5. A treatability study is run to investigate the rate at which a hazardous chemical X can be treated. The following data were collected at 25 o C. Time (Days) Concentration mg/L 1.0 1 0.81 3 .56 5 .36 7 .22 10 .14 a) Determine the order of the reaction by plotting data using Excel. b) What is the reaction rate? Provide correct units c) What is the half life for the reaction? d) What is the reaction rate at 30 o C if the following relation holds for reaction rates and temperature k T2 = k T1 * Θ (T2-T1) where T1 and T2 are temperatures and k T2 and k T1 is the reaction rate at the two temperatures Θ is a dimensionless temperature coefficient (Ranges from 1.056-1.13) Use Θ =1.1 for this problem...
