PbCl₂(s) ⇄ Pb²⁺(aq) + 2Cl⁻(aq)

Pb(CH₃COO)₂(s) → Pb²⁺(aq) + 2CH₃COO⁻(aq)

At lead acetate disolution, concentration of lead cations will increase. According to Le Chatelie's principle equilibrium will be displaced towards formation of solid lead chloride.

Answer:

The correct option is (a).

Explanation:

We need to find the product of given numbers.

First number = 29.5

Second number = 240

Product of two numbers = 29.5 × 240

= \dfrac{295}{10}\times 240

Zeroes from numerator and denominator get cancelled.

So,

=295\times 24\\\\=7080

Hence, the correct option is (a).
