Derive the best conditions for the formation of `NH_(3)`. Given,
`2NH_(3)hArrN_(2)+3H_(2)`, (`Delta H= +91.94 kJ)`

Text Solution

Verified by Experts

High pressure favours reactions showing decrease in moles i.e., forward reaction.
Low temperature favours reaction showing exothermic nature i.e., forward reaction.
More concentration of `N_(2)` and `H_(2)` also favours forward reaction.
