NH3 is more polar than AsH3, this is the same as comparing H2O and H2S.
nitrogen is more electronegative than the other elements, so there is a molecular dipole towards the nitrogen. NH3 is the most polar of the three.
AsH3 is Arsenic hydride.
AsH3 is a polar molecule because it is asymmetrical.
The oxidation number of hydrogen is almost always 1 and should be so in AsH3.

HCN will diffuse faster due to its lower molecular weight.

The Arsenic in AsH3 typically has a plus one charge. Therefore the H must have a -1 charge to create the compound.

3 because that is the number of bonds it has already
They have london forces between them. It is the weakest type of inter molecular force.
