The oxidation of SO(2) by O(2) to SO(3) ...

The oxidation of `SO_(2)` by `O_(2)` to `SO_(3)` is an exothermic reaction . The yield of `SO_(2)` will be maximum if

A

temperature is increased and pressure is kept constant

B

temperature is reducted and pressure is increased

C

both temperature and pressure is increased

D

both temperature and pressure are decreased.

Text Solution

Verified by Experts

The correct Answer is:
B
`2 SO_(2)(g)+O_(2)(g) hArr 2SO_(3)(g), Delta H =-ve `
Thus, increase of pressure or decrease of temperature will favour forward reaction.
