Question

For which of the following reactions does the equilibrium
constant depend on the units of concentration

(a) NO(g) = 1/2 N2(g) + 1/2 O2(g)

(b) Zn(s) + Cu^2+(aq) = Cu(s) + Zn^2+(aq)

(c) C2H5OH(l) + CH3COOH (l) =CH,COOC2H5(l) + H2O(l)
(Reaction carried in an inert solvent)

(d) COCI2(g) = CO(g) +Cl2(g)
​

Answer 1

The layer of soil which is just below the top-soil is called B-horizon. It is also known as sub-soil. The sub-soil is made up of slightly bigger rock particles than that of top-soil. ... The sub-soil has very little humus (decayed organic matter).
