The variation of heat of reaction with temperature at constant pressure is given by the ____________ law?
Correct answer: C. Kirchoff's
- A. Kelvin's
- B. Antoine's
- C. Kirchoff's
- D. None of these
Explanation
Kirchhoff's law relates the temperature dependence of the heat of reaction to the difference between the heat capacities of products and reactants. Antoine's equation describes vapor pressure, not reaction enthalpy.
