\(\mathrm{N}_{2}+3 \mathrm{H}_{2} \rightleftharpoons 2 \mathrm{NH}_{3}+\) Heat. What is the effect of the increase of temperature on the equilibrium of the reaction?
- A Equilibrium is shifted to the left
- B Equilibrium is shifted to the right
- C Equilibrium is unaltered
- D Reaction rate does not change
Answer & Solution
Correct Answer
(A) Equilibrium is shifted to the left
Step-by-step Solution
Detailed explanation
The given reaction, \(\mathrm{N}_{2}+3 \mathrm{H}_{2} \rightleftharpoons 2 \mathrm{NH}_{3}+\) Heat, is an exothermic reaction. \(\therefore\) According to Le-Chatelier's principle, on increase in temperature equilibrium is shifted to the left.
