Passage / Comprehension
The integral enthalpy of solution of one mole of H2SO4 in n mole of water is given by the equation ΔH = -75n/(n+1.8) kJ/mol. Determine ΔH for the following solutions:
Solution III: 1 mole of H2SO4 dissolved in large excess of water.
Options:
Answer:
D
Solution:
As n → ∞, the expression n/(n + 1.8) approaches 1. Therefore, Δ H → -75 kJ. The correct answer is (d).
