For a mixture of ethane 60%, acetylene 20%, and benzene 20% total mass of 250 kg is loaded into a reactor obeying the Carnot cycle, we want to know which produces more work when reacted with 25% fuel, 60% O2, 15% CO2 for 30 cycles. Calculate the amount of each fuel in the mixture; perform mass balance to obtain the amount of fuel that is actually reacting in the mixture if the reaction runs with 40% efficiency.

Running only ETHANE on an ideal engine, the first process is performed at standard pressure 30?C, in the heating and compression process the chambers have a pressure of 35 atm and a temperature of 575?C, calcualte the work performed in 30 cycles. Draw the PV diagram for the engine and label the state variable on their corresponding positions. Like (process 1 -> 2 ect. and describe waht kind of precess it is). How efficient is this engine?
