Vapour pressure correlation name check: The empirical equation log10 P = A − B/(t + C) for pure components is known as the ________ equation.

Introduction / Context:Correlations for pure-component vapor pressures are used in VLE design and simulation. A widely used empirical fit is the Antoine equation, convenient over moderate temperature ranges.

Given Data / Assumptions:

• Equation form: log10 P = A − B/(t + C).
• P is often in mmHg or bar depending on parameterization; t is temperature (commonly °C).

Concept / Approach:Recognize the canonical form and its name. The Antoine equation is a three-parameter modification of the Clausius–Clapeyron relation that improves fitting accuracy across limited ranges.

Step-by-Step Reasoning:

Verification / Alternative check:Process simulators store Antoine constants for thousands of compounds, confirming the naming convention.

Why Other Options Are Wrong:

• They do not correspond to the given functional form for vapor pressure.

Common Pitfalls:Using Antoine constants outside their valid temperature range; mixing units for P without matching the fitted constants.

Final Answer:Antoine equation
