Question

Write the expression for K_eq for the following reactions. In each case indicate whether the reaction is homogeneous or heterogeneous.

(a) N₂(g) + 3 H₂(g) 2 NH₃(g)

K_eq = P_NH3² / (P_N2 P_H2³)

K_eq = (P_N2) (3 P_H2) / 2 P_NH3

K_eq = P_N2 P_H2³ / P_NH3²

K_eq = 2 P_NH3 / ((P_N2) (3 P_H2))

The reaction is

(b) 4 HCl(g) + O₂(g) 2 H₂O(l) + 2 Cl₂(g)

K_eq = P_HCl⁴ P_O2 / P_Cl2²

K_eq = 2 P_Cl2 / (4 P_HCl P_O2)

K_eq = 4 P_HCl P_O2 / 2 P_Cl2

K_eq = P_Cl2² / (P_HCl⁴ P_O2)

The reaction is

(c) H₂(g) + I₂(g) 2 HI(g)

K_eq = 2 P_HI / (P_H2 P_I2)

K_eq = P_H2 P_I2 / 2 P_HI

K_eq = P_H2 P_I2 / P_HI²

K_eq = P_HI² / (P_H2 P_I2)

The reaction is

Expert Solution

Step 1

We can write keq by recalling this equation

A + B ---> C + D

Keq =( P_c × P_D) / (P_A × P_B)

P_x = partial pressure of X gas

A reaction said be homogeneous if all regents and product are in same state.
