Chapter 17: Q18P (page 775)

Balance each of the following examples of heterogeneous
equilibria and write its reaction quotient, Qc:
$(a) {Na}_{2} O_{2} (s) + {CO}_{2} (g) 饾啅 {Na}_{2} {CO}_{3} (s) + O_{2} (g) (b) H_{2} O (I) 饾啅 H_{2} O (g) (c) {NH}_{4} CI (s) 饾啅 {NH}_{3} (g) + HCI (g)$

Short Answer

Expert verified

A reaction quotient $(Q_{c})$ can create from a balanced chemical equation. Products and reactants are written in numerator and denominator with their coefficients as power and they are multiplied.

$(a) 2 {Na}_{2} O_{2} (s) + 2 {CO}_{2} (g) 饾啅 2 {Na}_{2} {CO}_{3} (s) + O_{2} (g) Q_{o} = \frac{{[{Na}_{2} O_{3}]}^{2} [O_{2}]}{{[{Na}_{2} O_{2}]}^{2} {[{CO}_{2}]}^{2}} (b) H_{2} O (I) 饾啅 H_{2} O (g) Q_{o} = \frac{[H_{2} O]}{[H_{2} O]} (c) 3 {NH}_{4} CI (s) 饾啅 3 {NH}_{3} (g) + 3 HCI (g) Q_{o} = \frac{{[{NH}_{3}]}^{3} {[HCI]}^{3}}{{[{NH}_{4} CI]}^{3}}$

Step by step solution

Reaction quotient of (QC) of (a)

$2 {Na}_{2} O_{2} (s) + 2 {CO}_{2} (g) 饾啅 2 {Na}_{2} {CO}_{3} (s) + O_{2} (g)$

Reaction quotient ,

$Q_{o} = \frac{{[N a_{2} O_{3}]}^{2} [O_{2}]}{{[N a_{2} O_{2}]}^{2} {[C O_{2}]}^{2}}$

Reaction quotient of (Qc) of (b)

$H_{2} O (I) 饾啅 H_{2} O (g)$

Reaction quotient ,

$Q_{o} = \frac{[H_{2} O]}{[H_{2} O]} = 1$

Reaction quotient of (Qc) of (c)

$3 {NH}_{4} CI (s) 饾啅 3 {NH}_{3} (g) + 3 HCI (g)$

Reaction quotient ,

$Q_{o} = \frac{{[N H_{3}]}^{3} {[H C I]}^{3}}{{[N H_{4} C I]}^{3}}$
