Asystem initially containing 2 mol c2h4 and 3 mol o2 undergoes the reactions: c2 h4(g) + _1 2 o2(g) → ⟨(ch2)2⟩o(g) c2 h4(g) + 3o2(g) → 2co2(g) + 2h2o(g) develop expressions for the mole fractions of the reacting species as functions of the reaction coordinates for the two reactions.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
