A flow of 90% CH4, 10% H2 is passed into a furnace at 900 K.
a. Determine whether carbon forms if the total pressure is 1.2 atm, carefully justifying your answer.
b. Calculate the composition ( expressed as a molar percentage) of the gaseous mixture at this temperature and pressure, assuming equilibrium. For methane
\(\DeltaG=8500 J/mole \) at 900 K.
Hint: ax \(ax^2+bx+c=0\)
