The vapour pressure of pure ether (molar mass 74 g/mol) at 293k is 588 m bar. A 10% (w/w) solutions of benzoic acid (molar mass=122 g/mol) was prepared in ether at 1293k. What will be the vapour pressure of solutions?

log 10=1 log 100=2 log 1000=3 and so on.

now,coming to your question,

log 0.130 is same as log 130/1000.

log 130/1000 = log 130 - log 1000

= 2.113 - 3

= -0.8860.

what is metastable equilibrium?

The experimental isotherms always seem to approach saturation at high pressure.Why this cannot be explained by Freundlich isotherm?
