Explanation:
As it is given that there are six electrons with four of them unpaired in the degenerate orbital.
As in a p-orbital there are only 3 sub-orbitals, that is, ,
, and
. In these sub-orbitals, a maximum of 6 electrons can be accommodated.
Th next higher orbital is d-orbital which can contain a maximum of 10 electrons. There are 5 degenerate orbitals present in a d-orbital.
So, a d-orbital can easily accommodate six electrons with four of them unpaired.
Thus, we can conclude that 5 degenerate orbitals are needed to contain six electrons with four of them unpaired.
Answer:
The new equilibrium total pressure will be increased to one-half to initial total pressure.
Explanation:
From the information given :
The equation of the reaction can be represented as;
From above equation:
2 moles of sulphur dioxide reacts with 1 mole of oxygen (i.e 2 moles +1 mole =3 moles ) to give 2 moles of sulphur trioxide
So; suppose the volume of this system is compressed to one-half its initial volume and then equilibrium is reestablished.
So if this process takes place ; the equilibrium will definitely shift to the side with fewer moles , thus the equilibrium will shift to the right. As such; there is increase in pressure.
Let the total pressure at the initial equilibrium be
and the total pressure at the final equilibrium be
According to Boyle's Law; Boyle's Law states that the pressure of a fixed mass of gas is inversely proportional to the volume, provided the temperature remains constant.
Thus;
P ∝ 1/V
P = K/V
PV = K
where K = constant
So;
PV = constant
Hence;
From the foregoing; since the volume is decreased to one- half to initial Volume; then ,
also;
Thus ;
Dividing both sides by
From ;
Thus; The new equilibrium total pressure will be increased to one-half to initial total pressure.
