Which of the following is NOT true about the thermodynamic standard state?
A. A pure liquid is in its standard state at 25C and a vapor pressure of 1.00 atm.
B. An aqueous solution is in its standard state at a concentration of 1.00 M.
C. A gas is in its standard state when its pressure is 1.00 atm and its temperature is 25C.
D. A solid is in its standard state when the atmospheric pressure is 1.00 atm and the temperature is 25C.
E. All of these are true.
The standard state for a gas is given in your chemistry textbook. The standard states for pure substances and solutes may also be given in the title of tables of thermodynamic properties. I think you can look this one up in your own textbook.
Good job contributing nothing GK. The answer is A.
