The question is incomplete. The complete question is :

Hydrogen is manufactured on an industrial scale by this sequence of reactions:

The net reaction is  :

Write an equation that gives the overall equilibrium constant in terms of the equilibrium constants and . If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator.

Solution :

    ...............(1)

 ...................(2)

On multiplication of equation (1) and (2), we get

 .................(4)

Comparing equation (3) and equation (4), we get

thats how its supposed to be
