You are to flash distill a mixture of 45 mole% of benzene and 5 mole% of toluene under isothermal conditions at 1 atm. equilibrium data for the benzene-toluene system can be approximated with a constant relative volatility of 2.5, where benzene is the more volatile component. a. plot the y-x diagram for benzene-toluene b. if 60% of the feed is evaporated, find the liquid and vapor composition

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
