Extracted text: Coal containing 5.0 wt% sulfur is burned at a rate of 1250 in a boiler furnace. All of the sulfur in the coals is min oxidized to SO2. The product gas is sent to a scrubber in which most of the SO, is removed, and the scrubbed gas then passes out of a stack to the atmosphere. An Environmental Protection Agency regulation requires that the gas in the stack must contain no more than 0.018 Ib, SO, Ib, coalburned" To test compliance with this regulation a flow meter and an SO, analyzer are mounted in the stack. The volumetric flow rate of the scrubbed gas is found to be 2,867 , and the SO, analyzer reading is 37. Calibration data for the analyzer are given in the table below. SO2 Analyzer Calibration Data SO, Concentration Analyzer Reading(0 – 100scale) m gas 0.30 10 0.85 28 2.67 48 7.31 65 18.2 81 30.0 90 Graph the calibration data in excel using exponential format for the trend line. You should get an equation of the form: y = aebz What are the values of a and b for the calibration curve?
