The %yield of ammonia as a function of time in the reaction `N _(2) (g) + 3 H _(2) (g) hArr 2 NH _(3) (g). Delta H lt 0 at (p , T _(1))` is given below. If this reaction is conducted at `(P_(1) T_(2)),` with `T_(2) gt T_(1)` the % yield of ammonia as a function of time is represented by

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
`N_(2)(g) + 3H_(2)(g) hArr 2NH_(3) Delta H lt 0` (exothermic). For exothermic reaction, high temperature facoures the reaction in backward direction i.e. yield of reaction decreases.
