Write the expression for equilibrium constant for the following reactions. If the concentrations are expressed in `mol L^(-1)`, give the units in each case.
a.

Explanation

a. `K_(c)=([NO_(2)]^(2))/([N_(2)O_(4)])`, units, `"mol" L`
b. `K_(c )=([SO_(3)]^(2))/([SO_(2)]^(2)[O_(2)])`, units, `"mol" L^(-1)`
c. `K_(c)=([NO]^(4)[H_(2)O]^(6))/([NH_(3)]^(4)[O_(2)]^(5))`, units, `"mol" L^(-1)`
d. `K_(c)=([NH_(3)]^(2))/([N_(2)][H_(2)]^(3))`, untis, `"mol"^(-2) L^(2)`
e. `K_(c)=([H_(2)][I_(2)])/([HI]^(2))`, no units
f. `K_(c)=[CO_(2)]`, units, `"mol" L^(-1)`
g. `K_(c)=([H_(2)]^(4))/([H_(2)O]^(4))`, no units
h. `K_(c)=([NO_(2)]^(4)[O_(2)])/([N_(2)O_(4)]^(2))`, units `"mol"^(3) L^(-3)`
