Answer:
Explanation:
Step 1. Determine the cell potential
<u> </u><u>E°/V</u><u> </u>
2MnO₄⁻ + 16H⁺ + 10e⁻ → 2Mn²⁺+ 8H₂O 1.507
<u>10Cl⁻ ⟶ 5Cl₂ + 10e⁻ </u> <u>-1.358 27
</u>
2MnO₄⁻ + 10Cl⁻ + 16H⁺⟶ 2Mn²⁺ + 5Cl₂ + 8H₂O 0.149
Step 2. Calculate K
The formula relating K and E is
E = 0.149 V
R = 8.314 J·K⁻¹mol⁻¹
T = 25 °C = 298.15 K
n = 10
F = 96 485 C/mol
The value of the equilibrium constant is

The answer of the question is C. Magnetic fields
Answer:
Explanation:
Bisulphate ion is a weak acid as it can form hydronium ion in water .
HSO₄⁻ + H₂O ⇄ SO₄⁻² + H₃O⁺
The equilibrium constant of this reaction is very small , hence bisulphate ion is very weak acid.
