Question

For two reactions in equilibrium in same container 1 A (s)
------> 2B (g) + C (g) ( Kp)1 = 4atm 2 D(s) ------> B (g) + E
(g) ( Kp)2 = 1atm Pressure of B ( g ) at equilibrium will be? ( Ans
is 3 atm, but how?)

Avni · Accepted Answer

Kp1 = PB2 PC=4
PB=4PC=21PC

Kp2= PB PE=1
PB=1PE

The equations cannot be solved further, some data is missing
