Geometry of ammonia molecule and the hybridisation of nitrogen involved in it are
sp3-hybridisation and tetrahedral geometry
sp3-hybridisation and distorted tetrahedral geometry
sp2-hybridisation and triangular geometry
None of the above
Be in BeCl2 undergoes
diagonal hybridisation
trigonal hybridisation
tetrahedral hybridisation
no hybridisation
For the reaction
PCl5(g) → PCl3(g) + Cl2(g)
ΔH = ΔE
ΔH > ΔE
ΔH < ΔE
None of these
B.
ΔH > ΔE
ΔH = ΔE + PΔV = ΔE+ngRT
PCl5(g) → PCl3(g) + Cl2(g)
Δng = n(p)(g) - n(r)(g) = 2-1 =1
∴ ΔH = ΔE + 1× RT
∴ ΔH > ΔE
Enthalpy (H) is equal to
internal energy (E)
product of pressure (p) and volume (V) of gas
internal energy (E)+ pV
work (W) done by a system
0.5 M ammonium benzoate is hydrolysed to 0.25 percent, hence, its hydrolysis constant is
2.5 x 10-5
1.5 x 10-4
3.125 x 10-6
6.25 x 10-6
