The desalination of sea water plant stops working due to which of the following reasons?

A The desalination of sea water plant stops working due to which of the following reasons?
B The pressure applied on the saline water was less than osmotic pressure.
C The pressure applied on the saline water was greater than osmotic pressure.
D The osmotic pressure application has no significance.

Verified Solution

Answer & Solution

Correct Answer

(B) The pressure applied on the saline water was less than osmotic pressure.

Step-by-step Solution

Detailed explanation

The pressure applied on the saline water was less than osmotic pressure.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
