Chapter 17: Q19P (page 775)

Balance each of the following examples of heterogeneous()
equilibria and write its reaction quotient, Qc:
$(a) H_{2} O (I) + {SO}_{3} (g) 𝆏 H_{2} {SO}_{4} (aq) (b) {KNO}_{3} (s) 𝆏 {KNO}_{2} (s) + O_{2} (g) (c) S_{8} (s) + F_{2} (g) 𝆏 {SF}_{6} (g)$

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.

$(a) H_{2} O (I) + {SO}_{3} (g) 𝆏 H_{2} {SO}_{4} (aq) Q_{o} = \frac{[H_{2} {SO}_{4}]}{[H_{2} O] [{SO}_{3}]} (b) 2 {KNO}_{3} (s) 𝆏 2 {KNO}_{2} (s) + O_{2} (g) Q_{o} = \frac{{[{KNO}_{2}]}^{2} [O_{2}]}{{[{KNO}_{3}]}^{2}} (c) S_{8} (s) + 24 F_{2} (g) 𝆏 8 {SF}_{6} (g) Q_{o} = \frac{{[{SF}_{6}]}^{8}}{[S_{8}] {[F_{2}]}^{24}}$

Step by step solution

Reaction quotient of (Qc) of (a)

$H_{2} O (I) + {SO}_{3} (g) 𝆏 H_{2} {SO}_{4} (aq)$

Reaction quotient $(Q_{C})$

$Q_{o} = \frac{[H_{2} S O_{4}]}{[H_{2} O] [S O_{3}]}$

Reaction quotient of (Qc) of (b)

$2 {KNO}_{3} (s) 𝆏 2 {KNO}_{2} (s) + O_{2} (g)$

Reaction quotient $(Q_{c})$

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

Reaction quotient of (Qc) of (c)

$S_{8} (s) + 24 F_{2} (g) 𝆏 8 {SF}_{6} (g)$

Reaction quotient $(Q_{c})$

$Q_{o} = \frac{{[S F_{6}]}^{8}}{[S_{8}] {[F_{2}]}^{24}}$
