An equilibrium mixture of CO, O2 and CO2 at a certain temperature contains 0.0010 M CO2 and 0.0025 M O2. At this temperature, Kc

pantera1 [17]

Answer:

$5.35 *10^{-4}$ M

Explanation:

Equation for the reaction is as follows:

$2CO_{(g)}$ + $O_{2(g)}$ ⇄ $2CO_{2(g)}$

By Applying the ICE Table; we have

$2CO_{(g)}$ + $O_{2(g)}$ ⇄ $2CO_{2(g)}$

Initial x 0.0025 M 0.0010 M

Change 0 0 0

Equilibrium x 0.0025 M 0.0010 M

$K_c =\frac{[CO_2]^2}{[CO]^2[O_2]}$

Given that $K_c = 1.4*10^2$ ; Then:

$1.4 *10^2 = \frac{(0.001)^2}{(x)^2(0.025)}$

$1.4 *10^2*0.025 = \frac{(0.001)^2}{(x)^2}$

$3.5 =( \frac{(0.001)}{(x)})^2$

$\sqrt {3.5} = \sqrt {( \frac{(0.001)}{(x)} )^2}$

$1.87=\frac{(0.001)}{(x)}$

$(x)= \frac{(0.001)}{1.87 }$

$x = 5.35 *10^{-4}$ M

∴ The equilibrium concentration of CO = $x = 5.35 *10^{-4}$ M

Predict the products of the following reaction: Zn(ClO₃)₂ (aq) + K₃PO₄ (aq)

nika2105 [10]

The products : Zn₃(PO₄)₂ (s) + KClO₃ (aq)

<h3>Further explanation</h3>

Given

reaction: Zn(ClO₃)₂ (aq) + K₃PO₄ (aq)

Required

The products

Solution

Double-Replacement reactions : an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

General formula :

AB + CD ⇒ AD + CB

One of the characteristics of the double replacement reaction is the presence of precipitated compounds

Zn(ClO₃)₂ (aq) + K₃PO₄ (aq) ⇒ Zn₃(PO₄)₂ (s) + KClO₃ (aq)

Zn₃(PO₄)₂ (s)⇒ precipitated compounds, so that this reaction can occur
