If for the reaction 2`NH_(3)`→`N_(2)`+`3H_(2)` the reaction is started with 2ml of `NH_(3)` the total volume of the gases in ml when the reaction is 50% complete will be:

For the reaction N_(2) + 3 H_(2) = 2 NH_(3) ,

For the reaction, N_(2)(g)+3H_(2)(g) to 2NH_(3)(g)

For the reaction, N_(2)3H_(2)rarr2NH_(3) rate is expressed as :

N_(2) + 3H_(2) to 2NH_(3) In this reaction, equivalent weight of N_(2) is :

Assertion (A) : In the reaction, N_(2)+3H_(2) rarr 2NH_(3) , the rate of reaction is different in terms of N_(2), H_(2) and NH_(3) . Reason (R ): The rate of reaction is equal to the rate of disappearance of a reactant or rate of formation of a Product.

In the equilibrium reaction N_(2)+3H_(2) Leftrightarrow 2NH_(3) , the sign of triangleH accompanying the reaction is
