In which among the following reactions, the formation of product is favoured by decreasing the temperature or volume ?

Answer»

`2SO_(3(g)) hArr 2SO_(2(g)) + O_(2(g)) -q`
`N_(2(g)) + O_(2(g)) hArr 2NO_(g) -q`
`4NH_(3(g)) + 5O_(2(g)) hArr 2NO_((g)) + 6H_(2)O_(g) , DeltaH=-ve`
`2NO_((g)) + O_(2(g)) hArr 2NO_(2(g)), DeltaH=-ve`

Solution :In the REACTION, `2NO + O_(2) hArr 2NO_(2) + ` Heat
Formation of product is favoured by decreasing the TEMPERATURE or volume.
