Answer to Question #114603 in Physical Chemistry for Akhil Rai

Question

draw a neat-labeled phase diagram of water system, and calculate degree of freedom of areas and curves in it. how many components are present in the following systems? fe(s) + h2o - feo(s) + h2 nacl(s) - nacl(aq)

Answer 1

F = C - P + 2

Where the phase is one (liquid, gas or solid) we have 1 - 1 + 2 = 2 F!

For the lines which are on border of 2 phases: 1 - 2 + 2 = 1 F!

For the triple point: 1 - 3 + 2 = 0 F!

fe(s) + h2o - feo(s) + h2 

# of components: Fe(s), H2O, FeO(s), H2 - 4!

nacl(s) - nacl(aq)

# of components: NaCl - 1!
