Question 41 - According to Raoult's law, the pressure when vapor is completely condensed, P = x(1) P(1) + x(2) P(2) ... + x(n) P(n) when x(1), x(2) ... x(n) are the mole fractions of component 1, 2 ... n and P(1), P(2) ... P(n) are the vapor pressures of component 1, 2 ... n. A vapor at 74 degree Celsius containing 70 mole % water and 30 mole % ethanol is to be completely condensed. At the temperature of 74 degree Celsius vapor pressure is 0.38 atm for water and 0.97 atm for ethanol. What is the minimum pressure the compressor must be operated?

Answer Posted / kang chuen tat (malaysia - pen
Answer 41 - Let component 1 is water, component 2 is ethanol, x(1) = 70 / 100 = 0.7, x(2) = 30 / 100 = 0.3, P(1) = 0.38 atm, P(2) = 0.97 atm, then P = x(1) P(1) + x(2) P(2) = 0.7 (0.38) + 0.3 (0.97) = 0.557 atm.
