Isotherm on an enthalpy-concentration diagram, for an ideal solution will be a __________________?
Correct answer: A. Straight line
- A. Straight line
- B. Sine curve
- C. Parabola
- D. Hyperbola
Explanation
For an ideal solution, the heat of mixing is zero, so the enthalpy varies linearly with composition at a fixed temperature. A linear relation is represented by a straight line.
