At high temperatures, steam decomposes into its elements according to the following equation.
2h2o(g) 2h2(g) + o2(g)
in one experiment at 1 atm pressure, it was found that 20% of the steam had been converted into
hydrogen and oxygen.
what are the values of the equilibrium partial pressures, in atm, of the components of this
equilibrium?
