Consider the chemical reaction N_(2)(g)+3H_(2)(g) rarr 2NH_(3)(g) . The rate of this reaction can be expressed in terms of time derivative of concentration of N_(2) (g) , H_(2)(g) or NH_(3)(g) . Indentifythe correct relationship amongst the rate expressions :

Answer»

RATE `= - d[N_(2)]//DT=-1//3d[H_(2)]//dt=1//2d[NH_(3)]//dt`
Rate `=-d[N_(2)]//dt=-3d[H_(2)]//dt=2d[NH_(3)]//dt`
Rate `=d[N_(2)]//dt=1//3d[H_(2)]//dt=1//2d[NH_(3)]//dt`
Rate = -`d[N_(2)]//dt=-d[H_(2)]//dt=d[NH_(3)]//dt`

Solution :(A) For the REACTION :
`N_(2) +3H_(2) rarr 2NH_(3)`
Rate =` -(d[N_(2)])/(dt) =-(1)/(3) (d[H_(2)])/(dt) = (1)/(2) (d[NH_(2)])/(dt)`
