Consider the following chemical equilibrium of the gas phase reaction at a constant temperature : $\displaystyle \mathrm{A}(\mathrm{g}) \rightleftharpoons \mathrm{B}(\mathrm{g})+\mathrm{C}(\mathrm{g})$
If p being the total pressure, $\displaystyle \mathrm{K}_{\mathrm{p}}$ is the pressure equilibrium constant and $\displaystyle \alpha$ is the degree of dissociation, then which of the following is true at equilibrium ?
Official answer
From NTA’s final answer key for this paper.
(1)
When p increases $\displaystyle \alpha$ decreases
