Which of the following is unrelated to estimating vapor pressure? (a) Antoine's Equation (b) Cox charts (c) Gibb's phase rule (d) Credible vapor pressure data

(c) Gibb's phase rule

Explanation:

Gibb's phase rule:

describe the relationship between the number of degrees fredoom in a closed system, the number of phases in equilibrium and the number of the system components.

f = c - p + 2

the above is no related to the estimation of the vapor pressure.
