Question

For which of the following reactions does the equilibrium constant depend on the units of concentration (A) NO(g) leftharpoons (1/2) N2(g) + (1/2) O2(g) (B) Zn(s) +Cu2+(aq) leftharpoons Cu(s) +Zn2+ (aq) (C) C2H5OH(l) +CH3COOH(l) leftharpoons CH3 COOC2 H5(l) +H2O(l) (Reaction carried in an inert solvent) (D) COCl2(g) leftharpoons CO(g) +Cl2(g)

Δ n = 1 for this change. So the equilibrium constant depends on the unit of concentration

Q. For which of the following reactions does the equilibrium constant depend on the units of concentration

$N O_{(g)} ⇌ \frac{1}{2} N_{2 (g)} + \frac{1}{2} O_{2 (g)}$

$Z n_{(s)} + C u_{(a q)}^{2 +} ⇌ C u_{(s)} + Z n_{(a q)}^{2 +}$

$C_{2} H_{5} O H_{(l)} + C H_{3} COO H_{(l)} ⇌ C H_{3} COO C_{2} H_{5 (l)} + H_{2} O_{(l)}$ (Reaction carried in an inert solvent)

$COC l_{2 (g)} ⇌ C O_{(g)} + C l_{2 (g)}$

$Δ n = 1$ for this change.

Q. For which of the following reactions does the equilibrium constant depend on the units of concentration

NO(g)​⇌21​N2(g)​+21​O2(g)​

Zn(s)​+Cu(aq)2+​⇌Cu(s)​+Zn(aq)2+​

C2​H5​OH(l)​+CH3​COOH(l)​⇌CH3​COOC2​H5(l)​+H2​O(l)​ (Reaction carried in an inert solvent)

COCl2(g)​⇌CO(g)​+Cl2(g)​

Δn=1 for this change. So the equilibrium constant depends on the unit of concentration

$N O_{(g)} ⇌ \frac{1}{2} N_{2 (g)} + \frac{1}{2} O_{2 (g)}$

$Z n_{(s)} + C u_{(a q)}^{2 +} ⇌ C u_{(s)} + Z n_{(a q)}^{2 +}$

$C_{2} H_{5} O H_{(l)} + C H_{3} COO H_{(l)} ⇌ C H_{3} COO C_{2} H_{5 (l)} + H_{2} O_{(l)}$ (Reaction carried in an inert solvent)

$COC l_{2 (g)} ⇌ C O_{(g)} + C l_{2 (g)}$

$Δ n = 1$ for this change.
