In a sulphuric acid plant, the secondary converter is a tray type converter, 2.3 m in diameter with the catalyst arranged in 0.45 m thick. the catalyst is in the form of cylindrical pellets 9.5 mm in diameter and 9.5 mm long. the void fraction is 0.35. the gas enters the converter at 675 k and i atm. its inlet composition is: so3 6.6, s02 1.7, 02 10.0, n2 81.7 mol%. the gas flow rate is 0.68 kg/m2 s. calculate the pressure drop through the converter. (gas viscosity- 0.032x 1 10 pa s)

answer; i believe the correct answer is (solid gold);

the answer is learned

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
