The particle diagram is shown in figure
As the atoms in the given diagram are closely placed to each other it means that the inter molecular forces are strong and the thermal energy of molecules is low .
When intermolecular interactions are strong and thermal energy is low the atoms or particles have a definite shape and volume
in case of gas the intermolecular forces are very low and the thermal energy of atoms is very high so they are in random motion and do not have a definite shape or volume
Now in the given examples
Rn , Xe and Kr all are noble elements and are infact noble gas
So the diagram could not be for these three
The only elements Ag (silver) is solid out of the given four elements so the particle diagram is of Ag only
Answer:
Explanation:
Given that:
From above:
To predict the effect of the addition of Br₂(g);
The addition of Br₂(g) will favor the equilibrium to shift to the left i.e. formation of NOBr
The removal of some NOBr will cause the equilibrium position to shift to the left side. This is because concentration on the left side is decreased and the concentration on the right side will be increased. Thus, the equilibrium will shift towards where the concentration is reduced which is the left side.
