Question

For the reaction $N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right),\Delta H=-ve$. The formation of $N{H}_3\left(g\right)$ is favored a

• A. High pressure and low temperature
• B. Low pressure and high temperature
• C. Low pressure and low temperature
• D. High pressure and high temperature

Answer 1

The correct option is A

High pressure and low temperature

High pressure will favor more of $N{H}_3$ as the forward direction involves decrease in gaseous species. Low temperature will favor more of $N{H}_3\left(g\right)$ as the forward direction is exothermic.
