o-na [289]

Answer:

9.044\times 10^{-3} is the value of the equilibrium constant for this reaction at 756 K.

Explanation:

COCl_2\rightleftharpoons CO+Cl_2

Equilibrium concentration of COCl_2

[COCl_2]=7.40\times 10^{-4} M

Equilibrium concentration of CO

[CO]=3.76\times 10^{-2} M

Equilibrium concentration of Cl_2

[Cl_2]=1.78\times 10^{-4} M

The expression of an equilibrium constant can be written as;

K_c=\frac{[CO][Cl_2]}{[COCl_2]}

=\frac{3.76\times 10^{-2}\times 1.78\times 10^{-4}}{7.40\times 10^{-4}}

K_c=9.044\times 10^{-3}

9.044\times 10^{-3} is the value of the equilibrium constant for this reaction at 756 K.

Potassium iodide reacts with lead(II) nitrate in this precipitation reaction: 2 KI(aq) + Pb(NO3)2(aq) → 2 KNO3(aq) + PbI2(s) Wha
andrew11 [14]

Answer:

a. 174 mL

Explanation:

Let's consider the following reaction.

2 KI(aq) + Pb(NO₃)₂(aq) → 2 KNO₃(aq) + PbI₂(s)

We have 155.0 mL of a 0.112 M lead(II) nitrate solution. The moles of Pb(NO₃)₂ are:

0.1550 L × 0.112 mol/L = 0.0174 mol

The molar ratio of KI to Pb(NO₃)₂ is 2:1. The moles of KI are:

2 × 0.0174 mol = 0.0348 mol

The volume of a 0.200 M KI solution that contains 0.0348 moles is:

0.0348 mol × (1 L / 0.200 mol) = 0.174 L = 174 mL
