012" The lonisation enthalpy also depends upon the electronic configuration of the atom It has been
observed that certain electronic configurations are more stable than others. For example hof files and
completely filled shell have extra stability associated with them. Consequently it is difficult to remove
electron from these stable configurations,
Answer the following on the basis of the above paragraph
Why the noble gases have highest value of ionisation enthalples in their respective period ?
Out of u, Be, Mg, Al, P and Cl which have completely filled and half-filled orbitals consequently
large ionisation enthalples

Q15* The change in pressure has also an important effect on equilibrium which involve gaseous substances
and there is change in total number of moles of gases in reactants and products. If the pressure of the
gaseous system is increased the volume occupied by the system will decrease and the equilibrium will shift
towards that direction in which there are fesser no of moles of gaseous substances.
Answer the following on the basis of the above paragraph:
(0)
According to which principle there is shift in the equilibrium of gaseous system if pressure is
Increased
If pressure is increased in which direction the equilibrium will shift in the following reaction
N2(g) + 3H2(g)2NHxg)
