`N_(2)+3H_(2)hArr2NH_(3)`
Which is correct statement if `N_(2)` is added at equilibrium condition?
A. If `N_(2)` is added at equilibrium condition, the beacause according to `Iind` law of thermodynamics the entrophy must increase in the direction of spontaneous reaction.
B. The condition for equilibrium is `2DeltaG_(NH_(3))=3DeltaG_(H_(2))+DeltaG_(N_(2))` where G is Gibbs free energy per mole of the gaseous species measured at that partical pressure.
C. Addition of catalyst does not change `K_(P)` but changes `DeltaH`
D. At 400K addition of catlyst will increase forward reaction by 2 times while reaverse reaction rate will be changed by `1.7` times.
