Which of the following is the best description of an oxidation process

spin [16.1K]

Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases. Oxidation doesn't necessarily involve oxygen!

Answer: The equilibrium partial pressure of sulfur dioxide, oxygen and sulfur trioxide is 0.366 atm, 0.443 atm and 0.154 atm respectively.

Explanation:

We are given:

Initial partial pressure of sulfur dioxide = 0.52 atm

Initial partial pressure of oxygen = 0.52 atm

Initial partial pressure of sulfur trioxide = 0 atm

For the given chemical reaction:

$2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)$

Initial: 0.52 0.52

At eqllm: 0.52-2x 0.52-x 2x

The expression of $K_p$ for above equation follows:

$K_p=\frac{(p_{SO_3})^2}{(p_{SO_2})^2\times p_{O_2}}$

We are given:

$K_p=0.40\\\\p_{SO_3}=2x\\\\p_{SO_2}=0.52-2x\\\\p_{O_2}=0.52-x$

Putting values in above equation, we get:

$0.40=\frac{(2x)^2}{(0.52-2x)^2\times (0.52-x)}\\\\x=-1.13,-0.402,0.077$

Neglecting the negative values because partial pressure cannot be negative.

So, x = 0.077

Equilibrium partial pressure of sulfur dioxide = $(0.52-2x)=(0.52-(2\times 0.077))=0.366atm$

Equilibrium partial pressure of oxygen = $(0.52-x)=(0.52-0.077)=0.443atm$

Equilibrium partial pressure of sulfur trioxide = $2x=(2\times 0.077)=0.154atm$

Hence, the equilibrium partial pressure of sulfur dioxide, oxygen and sulfur trioxide is 0.366 atm, 0.443 atm and 0.154 atm respectively.

2H2 + O2 2H2O

Licemer1 [7]

Answer:

c ) 8

Explanation:

Given data:

Number of moles of water produced = ?

Moles of hydrogen react = 8 mol

Solution:

Chemical equation:

2H₂ + O₂ → 2H₂O

Now we will compare the moles of hydrogen and water.

H₂ : H₂O

2 : 2

8 : 8

Thus, 8 moles of water will produced.
