Solution

As the half-life is independent of the initial concentration of the reactants. Hence, it is a first-order Reaction. The formula for the half-life of the first-order reaction.
t½= 0.693/K

Solution

A. N-Methylpropan-2-amine

Solution

Chromium belongs to group number 6 and its oxidation state in K₂Cr₂O₇ is +6
i.e., K₂Cr₂O₇
1 × 2 + 2x + (-2 × 7) = 0
⇒ 2 + 2x – 14 = 0
⇒ 2x – 12 = 0
⇒ 2x = 12
⇒ x = 6
Thus, the formula of the oxo-anion is K₂Cr₂O₇

Solution

Given: (H+) = 349.6 S cm mol ⁻ and (CH3COO ⁻)= 40.9 S cm mol ⁻.</p>
