Its acidic not acetic.
It decreases down the group because bascity increases as due to the addition of more number of shells to the atoms as we go top to the bottom and hence more shielding occurs.
.
NF3 is exothermic compound as F is the most electronegative elemnet ever and hence to detach very high amount of energy would be required and thus release of energy.
