Just a few short questions:
I have to define dynamic equilibrium state in terms of a) reaction rates b) change in observable properties and c) energy and entropy state
I also have to explain in which of the following closed containers has the greatest vapour pressure.
the choices are a) 1L container with 5mL of water held at 20degreescelcius
b) 2L container with 15mL of water held at 30degcel
c) 3L containter with 500mL at 25degcel
finally, ethanol and water are completely miscible; that is, they dissolve in each other in all propertions:
a) when the two substances are mixed, is randomness increased or decreased?
b) heat is liberated in the dissolving process. Does the tendency towards minimum energy favour the separated pure substances, or the solution of one in the other?
c) In view of the tendicies listed in a) and b) above, explain why water and ethanol are completley miscible.
Thanks for the help.
