Passage / Comprehension
The integral enthalpy of solution of one mole of CaCl2 in n mole of water is given by the equation ΔH = -60n/(n+3) kJ/mol. Determine ΔH for the following solutions:
Solution III: 1 mole of CaCl2 dissolved in large excess of water.
Options:
Answer:
D
Solution:
As n → ∞, n/(n + 3) → 1, so ΔH → -60 kJ. It is determinate. Ans (d).
