The first-order reaction A→B takes place in an isothermal CSTR. The feed temperature is 20°C, and the reactor is held at 120°C by heat exchange. A jacket is used to keep the temperature of the reactor and this jacket is kept at this temperature by the water bath. The water bath is 40°C. The temperature of the water bath was measured with PT100 and NTC, and 5 different data were obtained. Water bath T(°C) 1 2 3 4 5 Pt100 40.3 41.2 39.8 40.5 42.0 NTC 41.1 39.7 41.7 40.1 40.2 a) Calculate the average, standard deviation, and percentage error for each measurement (12p) b) Calculate the accuracy (3p) c) Compare the precision, and accuracy of the devices and discuss the reasons (4p) d) Suggest the most appropriate temperature measurement device (3p) e) Explain the reasons for deviations from the actual temperature (3p) Standard deviation: σ = $$ \sqrt{\frac{1}{n} \sum_{i=1}^{n} d_i^2} $$ %Error = $$ \frac{\sigma^2}{\bar{x}} $$ *100

Compute the three-year implied forward rate two years from now, given the information provided in preceding table. State the assumption underlying the calculation of the implied forward rate (6 marks) B. What is the value of a 5-year, 6.5% coupon Treasury note. Interest paid annually Assume $100 par value. (6 marks) C. If the price of 6-year, 7% coupon Treasury security is $98.00. What is the theoretical 6-year spot rate? Interest paid annually. (6 marks) Question 5 [16 marks] A. Assume that you purchase a 4-year $1,000 par value bond, with an 8% coupon. and a yield of 10%. After you purchase the bond, one-year interest rates are as foilow, year 1 = 10%, year 2 = 11%, year 3 = 12% (these are the reinvestment rates). Calculate the realized horizon yield if you hold the bond to maturity. Interest is paid annually. (6 marks) B. A $1,000, 7%, 25-year bond has a yield of 5.5%. If the yield remains unchanged how much will the bond value increase by in the next three years? Assume interest is paid semi-annually. (5 marks) C. How you would use a zero-coupon bond to immunize a bond portfolio? Discuss why a zero-coupon bond is an ideal instrument in this regard. (5 marks)
