    Could someone please help me with all parts of this question? QUESTION 4 In an electrostatic precipitator, particles are removed from air by ionisation. The ons and electron flow ionised particles are diverted towards an earthed plate, build up on the collection plates and are removed from the air stream. The magnitude of the resulting current density reaching the earthed plate is well described by the so-called Warburg law: ITOTAL MARKS: 25] Earthed plate ,, ,, J-0 elsewhere with θ...

    Could someone help me breakdown this problem and figure out how to calculate it? I have added the balanced equation and broke down the products from the reactants. I have also looked up the thermodynamic data. You are comparing the efficiencies of propane (C3H8) gas and ethanol (C2H5OH) as fuels. Assume all reactants and products are in the gas state. I have the balanced equation for C3H8 and C2H5OH as C3H8 +5O2------>3CO2 + 4H2O For the products, I have 3CO2...
