(a) Write cathode and anode half-reactions, and a net reaction (balanced) for a low-temperature direct methanol fuel cell (assuming complete oxidation of fuel). Calculate the theoretical thermodynamic potential difference for an ideal direct methanol fuel cell (assuming complete oxidation of fuel) at 25.0 and 185 °C (F= 96485.3 Cmol-'). Standard thermodynamic data: AH:200) = -286 kJmol. Shop = 70.0 JK 'mol A.Hco2 = -394 kJmol. Sco2 = 214...

Please tell me if these workings are correct? If not, could
you please help me correct my mistakes. Im not sure if I need to
subtract the atmospheric pressure - and if I have to, I cant
understand how to calculate it with what ive been given.

The elementary reversible reaction A + B 2C occurs in the liquid phase in isothermal CSTR. A stream containing equimolar amounts of A and B in a solvent enters. the reactor, and the conversion of A is measured to be 60%. The equilibrium conversion o A under the same inlet conditions is known to be 80%. The volumetric flowrate into the process is to be...

Hi,
can anyone please help me with this? i have no clue how to define
if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...

Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!
