Vapor Pressure Calculator

What is Vapor Pressure Calculator?

The vapor pressure calculator is a powerful tool for performing vapor pressure calculations in chemistry. It simplifies the process of determining the vapor pressure of a substance at different temperatures using the given formula:

Vapor Pressure Formula
P₂ = P₁ × exp[(ΔHv/R) × (1/T₁ – 1/T₂)]

Where:

• P₁ is the vapor pressure at the known temperature (T₁)
• P₂ is the vapor pressure of interest at temperature (T₂)
• ΔHv is the molar enthalpy of vaporization (in joules per mole)
• R is the constant (8.3145 J/mol·K)
• T₁ and T₂ are the temperatures in Kelvin

Simply input the known values and calculate vapor pressure using this convenient tool.
