Answer 2

Answer:

Explanation:

Answer :

1

Solution :

We have,

10 moleCO(g)10+x+10 moleH2O(g)10+x⇔10 moleCO2(g)10−x+10 moleH2(g)10−xInitial molesMoles at eqb. or concentration at eqb.

where x is the number of moles of each reactant changed to the products at equilibrium.

K=(10−x)2(10+x)2=4/9(given) or 10+x10−x=3/2,x=2

Mole percent of H2(g) at equilibrium =10−x40×100=20
