Explanation:
Since, the given reaction is as follows.
Initial: 36.1 atm 0 0
Change: 2x x x
Equilibrium: (36.1 - 2x) x x
Now, expression for of this reaction is as follows.
As the initial pressure of NO is 36.1 atm. Hence, partial pressure of at equilibrium will be calculated as follows.
x = 18.1 atm
Thus, we can conclude that partial pressure of at equilibrium is 18.1 atm.
Answer:
Carbon dioxide is a pure substance that is a compound
Explanation:
First consider the properties of a pure substance:
•made of only one type of atom or molecule
•has a well-defined melting point, boiling point, colour, odour, density and solubility.
Answer:
Explanation:
Electrochemical corrosion of a metal is its spontaneous reaction with oxygen.
Let's compare the standard reduction potentials for a hypothetical metal M with that of oxygen.
<u>E°/V</u>
O₂(g) + 2H₂O(ℓ) + 4e⁻ ⇌ 4OH⁻(aq) 0.4
M²⁺(aq) + 2e⁻ ⇌ M(s) -0.1
To react spontaneously with O₂, the metal must have a
<u>E°/V
</u>
2 × [M(s) ⇌ M²⁺(aq) + 2e⁻ ] 0.1
1 × <u>[O₂(g) +2H₂O(ℓ) + 4e⁻ ⇌ 4OH⁻(aq)] </u> <u>0.4
</u>
2M(s) + O₂(g) + 2H₂O(ℓ) ⇌ 2M²⁺(aq) + 4OH⁻(aq) 0.5
Only then will we get a positive for the overall cell potential and a spontaneous reaction.
The process is called evaporation
