The % yield of ammonia as a function of time in the reaction, `N_(2)(g)+3H_(2)(g)hArr2NH_(3)(g)'DeltaHlt0`
at `(p,T_(1))` is given below

If this reaction is conducted at `(p,T_(1))`, with `T_(2)gtT_(1)` the % yield by of ammonia as a function of time is represented by

Options

A.
B.
C.
D.

Answer

B

Explanation

Initially on increasing temperature rate of reaction will increase, so % yield will also increase with time. But at equilibrium % yield at high temperature `(T_(2))` would be less than at `T_(1)` as reaction is exothermic so the graph is
