CCl ₄ and acetone form a non-ideal solution at room temperature in a copper container. For this process, the true statement(s) is (are) :

Options

  1. AG is positive
  2. BS _ system is positive
  3. CS _ surroundings 0
  4. DH 0

Correct answer

D. H 0

Step-by-step solution

array ll G =- ve , S _ system & =+ ve Always for solution formation. S _ surr. 0 & Heat absorbed by solution from surrounding. H 0 & For this solution as CCl ₄ is non-polar but & acetone is polar array
