The vapor pressures (in torr) of solid and liquid chlorine are given by ln ( p s ) = 24.320 − 3777 k t ln ( p l ) = 17.892 − 2669 k t where t is the absolute temperature. calculate the temperature and pressure at the triple point of chlorine.

Explanation:

Triple point is that temperature and pressure for a substance at which the chemical substance coexists in liquid, solid and gaseous state with mutual equilibrium.

Given expressions of vapor pressure:

........................................(1)

..........................................(2)

Equating the vapor pressure of two phases of chlorine:

The vapor pressure at this temperature:

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )
