Question

The preparation of ammonia by Haber's process is an exothermic reaction. If the process follows the following temperature pressure relationship for its $\%$ yield, then for temperatures $T_{1}$ $T_{2}$ and $T_{3}$ the correct option is

• A. $T_{3} >T_{2} >T_{1}$
• B. $T_{1} >T_{2} >T_{3}$
• C. $T_{1}=T_{2}=T_{3}$
• D. nothing could be predicted.

Answer 1

Answer: (B)

For exothermic reactions as temperature increases yield decreases thus, $T_{1}>T_{2}>T_{3}$
