Question

Standard free energies of formation (in J/mol ) at 298K are -x -y and -z for H_(2)O(ell) CO_(2)(g) and CH_(4)(g) respectively.The value of E_( cell ) (in volts) for methane - oxygen fuel cell is res (z-y-2x)/(4F) (y+2x-z)/(8F) (z-y-2x)/(2F)​

Answer 1

Answer:

A common rocket propellant combination consists of hydrogen fuel and oxygen. Consider a hydrogen-oxygen reaction given by

(4.61)

Here we have one mole of hydrogen fuel reacting with one mole of oxygen to form six species from two elements. Atom conservation
