An equation for calculating vapour pressure is given by, log10 P = A - B(t + c). This is called the________________?
Correct answer: B. Antoine equation
- A. Kistyakowsky equation
- B. Antoine equation
- C. Kopp's rule
- D. Trouton's rule
Explanation
The Antoine equation correlates vapour pressure with temperature, commonly written as log₁₀P = A − B/(T + C). Kopp's rule concerns solid heat capacities, while Trouton's rule concerns entropy of vaporisation.
