Predict the sign of `DeltaS` for each of the following process:
a. `O_(2)(g) rarr 2O(g)`
b. `N_(2)(g) +3H_(2)(g) rarr 2NH_(3)(g)`
c. `C(s) +H_(2)O(l) rarr CO(g) +H_(2)(g)`
d. `Br_(2)(l) rarr Br_(2)(g)`
e. `N_(2)(g, 10 atm) rarr N_(2)(g,1atm)`
f. Desalination of water.
g. Devitrification of glass
h. Hard boiling of an egg
i. `C(s, "graphite") rarr C(s, "diamond")`

Explanation

a. `+ve =` increase in the number of gas molecules
b. `-ve =` Decrease in the number of molecules
c. `+ve =` Increase in the number of moles
d. `+ve =` Increae in the number of moles
e. `+ve =` Entropy increases on expansion
f. `-ve =`Desalination is the opposite of solution
g. `-vec=` It is crystallisation of supercooled liquid
h. `+ve =` Denaturation of protein takes place. Structure of protein change `(3^(@) to 1^(@))` from helical sturature of random configuration.
i. `-ve =` Diamond being harder solid, would be expected to have more restricted atomic motion within the crystal.
