\huge \orange {\mathbb {Answer}}

Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.

For the reaction CO(g) + 3 H2(g) ⇌ H2O(g) + CH4(g) , Kc = 190 at 1000 K. If a vessel is filled with these gases such that the in

Answer:

<u>the reaction will shift to the left </u>and produce more reactants

Explanation:

Step 1: data given

Kc = 190

Temperature = 1000 K

[CO] = 0.025 M

[H2] = 0.045 M

[H2O] = 0.025 M

[CH4] = 0.046 M

When Q=Kc, the system is at equilibrium and there is no shift to either the left or the right.

When Q<Kc, there are more reactants than products. As a result, some of the reactants will become products, causing the reaction to shift to the right.

When Q>Kc, there are more products than reactants. To decrease the amount of products, the reaction will shift to the left and produce more reactants

Step 2: The balanced equation

CO(g) + 3 H2(g) ⇌ H2O(g) + CH4(g)

Step 3: calculate Q

Q = [H2O][CH4] / [CO][H2]³

Q = (0.025*0.046) / (0.025*0.045³)

Q = 504.8

Q > Kc

This means there are more products than reactants. To decrease the amount of products, <u>the reaction will shift to the left </u>and produce more reactants

Chemists studied the formation of phosgene by sealing 0.96 atm of carbon monoxide and 1.15 atm of chlorine in a reactor at a cer
lukranit [14]

Answer:

3.9

Explanation:

Let's consider the following reaction at equilibrium.

CO(g) + Cl₂(g) ↔ COCl₂(g)

We can find the pressures at equilibrium using an ICE chart.

       CO(g) + Cl₂(g) ↔ COCl₂(g)

I       0.96       1.15            0

C        -x           -x            +x

E    0.96-x    1.15-x           x

The sum of the partial pressures is equal to the total pressure.

pCO + pCl₂ + pCOCl₂ = 1.47

(0.96-x) + (1.15-x) + x = 1.47

2.11 - x = 1.47

x = 0.64

The pressures at equilibrium are:

pCO = 0.96 - x = 0.32 atm

pCl₂ = 1.15 - x = 0.51 atm

pCOCl₂ = x = 0.64 atm

The pressure equilibrium constant (Kp) is:

Kp = pCOCl₂ / pCO × pCl₂

Kp = 0.64 / 0.32 × 0.51

Kp = 3.9
