Vapor–liquid equilibrium data

Table data (above) obtained from ''CRC Handbook of Chemistry and Physics'' 44th ed. The (s) notation indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid. Vapor-pressure formula for ammonia:Lange's Handbook of Chemistry, 10th ed. page 1436. : log₁₀''P'' = ''A'' – ''B'' / (''T'' − ''C''), where ''P'' is pressure in k Pa, and ''T'' is temperature in

kelvin The kelvin, symbol K, is the primary unit of temperature in the International System of Units (SI), used alongside its prefixed forms and the degree Celsius. It is named after the Belfast-born and University of Glasgow-based engineer and phys ...
