In an ideal rankine cycle (1-2-3-4-1 where 1 is turbine inlet, 2 is turbine exit) the following data are supplied: h1 = 3445, h2 = 2467, h3 = 340, and h4 = 344.
a) determine the back work ratio in percent (bwr is pumping power divided by turbine power) %
b) if the net power produced by the plant is 100 mw, determine the mass flow rate through the cycle. kg/s
c) the thermal efficiency of the cycle in percent.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
