Give the mechanism of the following reactions:
(a) In lead chamber process, NO(g) is used as catalyst in the oxidation of `SO_(2)` to `SO_(3)`.
(b) NO(g) catalyses the decomposition ozone to oxygen.
(c) Ozone layer depletion by freon or teflon.

………..is used as catalyst for oxidation of SO_2 to SO_3 in contact process.

Name the catalyst used for the oxidation of SO_2 to SO_3 in contact process.

What is the catalyst used for oxidation of SO_(2) to SO_(3) in lead chamber process for manufacture of sulphuric acid ?

What is the catalyst used for oxidation of SO_(2) to SO_(3) in lead chamber process for manufacture of sulphuric acid ?

What is the catalyst used for oxidation of SO_2 to SO_3 in lead chamber process for manufacture of sulphuric acid ?

Calculate the work done in each of the following reactions State whether work is done on or by the system (a) The oxidation of one mole of SO_(2) at 50^(@)C 2SO_(2(g)) + O_(2(g)) to 2SO_(3(g)) (b) Decomposition of 2 moles of NH_(2) NO_(3) at 100^(@)C NH_(4)NO_(3(s)) to N_(2) O_((g)) + 2H_(2)O_((g))
