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?
