Answer:
Explanation:
Hello,
In this case, the Gibbs free energy of that reaction is computed by computing the equilibrium constant as:
Hence the Gibbs free energy:
Best regards.
Answer:
•Matter is made up of smallest indivisible particle named as atom.
•All atom of same element have equal atomic mass and identical properties.
•Compounds are made up two or more different types of atoms.
•In a chemical reaction rearrangement of atoms takes place.
•Atoms of different elements differ in mass and size.
<h2>Solutions:</h2>
<u>Case a:</u> Finding pH for [H⁺] = 1.75 × 10⁻⁵ mol/L :
As we know pH is given as,
pH = -log [H⁺]
Putting value,
pH = -log [1.75 x 10⁻⁵]
pH = 4.75
<u>Case b:</u> Finding pH for [H⁺] = 6.50 × 10⁻¹⁰ mol/L :
As we know pH is given as,
pH = -log [H⁺]
Putting value,
pH = -log [6.50 × 10⁻¹⁰]
pH = 9.18
<u>Case c:</u> Finding pH for [H⁺] = 1.0 × 10⁻⁴ mol/L :
As we know pH is given as,
pH = -log [H⁺]
Putting value,
pH = -log [1.0 × 10⁻⁴]
pH = 4
<u>Case d:</u> Finding pH for [H⁺] = 1.50 × 10⁻⁵ mol/L :
As we know pH is given as,
pH = -log [H⁺]
Putting value,
pH = -log [1.50 × 10⁻⁵]
pH = 4.82
