Question
Indicate whether the following statements are true or false. If false, explain in one sentence what makes the statement false.
(a) Graphite is a metastable state of diamond.
(b) The chemical potential of a system is more sensitive to pressure for condensed phases than for gases.
(c) For a two-component system, the chemical potential of one component is independent of the other component.
(d) For a spontaneous change, energy and matter become more organized.
(e) The triple point represents the maximum temperature at which a gas phase is stable.
(f) The Helmholtz energy represents the maximum work available to a system.
Explanation / Answer
a) False
The change in enthalpy of carbon in diamond from to graphite is negative.
Hence, Daimond is metastable state.
c) false
the chemical potential of two components are related to each other.
d) false
For a spontaneous change, energy and matter become more un-organized.
e) False
At triple point, all the three phases are coexist in equilibrium.
f) True
