One mole of methane gas (CH4) is heated isobarically at a pressure of 1 atm from 82.2 ° C to 211.9 ° C in a cylindrical piston device with condensed steam from saturated vapor to fully condensed at 250 ° C. a. If methane is considered an ideal gas, calculate ΔU, ΔH, ΔS, ΔG (in Joule) b. Calculate work (W) and heat involved (Q), (in Joule). c. Calculate the change in environment, and the total entropy generated by this process (in J / K). Known : Cp methane = 2.62 kJ / kg K S(298.15 K; 1 atm) = 186.3 kJ / kmol K.
*Someone please post the answer maximum 1 hour later because I’m now in the middle of an exam. Thankyou so much for understanding and please help me.

1.f) Methane gas (CH4) enters a combustion chamber at a rate of 3 kg/sec at a temperature of 25 °C. A 200% theoretical air is supplied at a temperature of 400K. At the middle of methane combustion process (i.e., after 50% of methane gas is burnt), liquid propane (C3H8) at 25°C is injected at a rate that produces neither CO nor O2 in the flue gases. Assume steady state and adiabatic process at 1 atm, calculate the following i. The...

A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5427 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.417 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant.
