In what "capacity" is sodium chloride react with sulphuric acid

It depends of the concentration and of the sulfuric acid and possibly the concentration and the volume of the NaCl.
IF you use 98% H2SO4 and anhydrous NaCl, You will get huge, corrosive, white fumes of HCl gas being produced. These are quite dangerous, HIGHLY corrosive to metal surfaces, and are toxic. they dissolve in your saliva, lungs and eyes to produce Hydrochloric Acid. In short, only do this IF YOU ARE PREPARED.
IF you use either dilute H2SO4 or aqueous NaCl, you will have a very concentrated HCl solution after a small amount of HCl gas is released. this might or might not fume in air, depending on the concentration of HCl.
IF you use dilute H2SO4 and aqueous NaCl in which there is a decent amount of water, most likely all the HCl gas will dissolve to produce Hydrochloric Acid. Again, this solution is acidic, but less than the previous one
IF you use insufficient NaCl/H2O, then you will also get the formation of a solid cake of NaHSO4 (Sodium Bisulphate). If you have enough water and NaCl, then you will produce mainly Na2SO4. this can be seen in the equations:
NaCl+H2SO4—> NaHSO4 +HCl
2NaCl+H2SO4—> Na2SO4+2HCl
