# Write an equation for an equilibrium system that would lead to the following expressions ( a − c ) for K.(a) K = ( P co ) 2 ( P H 2 ) 5 ( P C 2 H 6 ) ( P H 2 O ) 2 (b) K = ( P NH 3 ) 4 ( P O 2 ) 5 ( P NO ) 4 ( P H 2 O ) 6 (c) K = [ ClO 3 − ] 2 [ Mn 2 + ] 2 ( P cl 2 ) [ MNO 4 − ] 2 [ H + ] 4 ; liquid water is a product

Interpretation Introduction

(a)

Interpretation:

For the given expression of equilibrium constant, the equation for the equilibrium reaction needs to be determined.

K=(PCO)2(PH2)5(PC2H6)(PH2O)2

Concept introduction:

The system is said to be in equilibrium if the there is no change in the partial pressure or concentration of reactant and product takes place.

For a general reaction as follows:

A(g)+B(g)C(g)+D(g)

The expression for the equilibrium constant is represented as follows:

K=(PC)(PD)(PA)(PB)

Here, to calculate the equilibrium constant, the values of partial pressure of all the species in reactant and product side are required.

Explanation

The given expression for the equilibrium constant, K is as follows:

K=(PCO)2(PH2)5(PC2H6)(PH2O)2

Here, CO (g) and H

Interpretation Introduction

(b)

Interpretation:

For the given expression of equilibrium constant, the equation for the equilibrium reaction needs to be determined.

K=(PNH3)4(PO2)5(PNO)4(PH2O)6

Concept introduction:

The system is said to be in equilibrium if the there is no change in the partial pressure or concentration of reactant and product takes place.

For a general reaction as follows:

A(g)+B(g)C(g)+D(g)

The expression for the equilibrium constant is represented as follows:

K=(PC)(PD)(PA)(PB)

Here, to calculate the equilibrium constant, the values of partial pressure of all the species in reactant and product side are required.

Interpretation Introduction

(c)

Interpretation:

For the given expression of equilibrium constant, the equation for the equilibrium reaction needs to be determined.

K=[ClO3]2[Mn2+]2(PCl2)[MnO4]2[H+]4

Concept introduction:

The system is said to be in equilibrium if the there is no change in the partial pressure or concentration of reactant and product takes place.

For a general reaction as follows:

A(g)+B(g)C(g)+D(g)

The expression for the equilibrium constant is represented as follows:

K=(PC)(PD)(PA)(PB)

Here, to calculate the equilibrium constant, the values of partial pressure of all the species in reactant and product side are required.
