Question

a gaseous mixture consists of N2 H2 and NH3 in equilibrium what is the number of phases​

Answer 1

Answer:

N2(g)+3H2(g)⇌2NH3(g)

Qp=[PN2][PH2]3[PNH3]2

Qp=2×1332

Qp=4.5

Kp=4.28×10−5atm−2

Qp>Kp

Thus, the reaction will favour in the backward direction.

Answer 2

Answer:

In the gaseous mixture consisting of N2 H2 and NH3 in equilibrium, there is only one phase that is gaseous. So the number of phases is 3.

Explanation:

• All the reactants and products are in the same phase, in a homogeneous system.
• For example, in the gaseous reaction, N2(g)+3H2(g)⇌2NH3(g) reactants and products are in the homogeneous phase.
• In the above reaction, the reactants   N2(g), 3H2(g), and the product 2NH3(g) are in one phase, which is the gaseous phase, and hence the number of phases is 3.
