a 1. A) When plotted as y vs R on semi-log paper, the calibration curve for a carbon monoxide (CO) gas analyzeryielded a straight line passing through the following points R 0.002094 25 0.06935 95 where y is the mole fraction of CO in the gas stream and R is the gas analyzer reading. Determine the calibration formula. (8 marks) B) Part of the by-product from a processing plant is a stream containing 53% H3PO4, 22% C2H4O2 and 25% H20 by mass. It is required to concentrate this acid to produce one containing 61% H3PO4 and 29% C2H4O2 by adding concentrated phosphoric acid containing 95% H3PO4 and concentrated acetic acid containing 91% C2H4O2. If the mass flow rate of the by-product acid steam is 130 kg h-2, calculate the mass flow rates of the concentrated acid streams and the total flow rate of the final acid mixture. (15 marks)
