Q1

Consider the following chemical equilibrium of the gas phase reaction at a constant temperature :
\(\mathrm{A}(\mathrm{g})⇌\mathrm{B}(\mathrm{g})+\mathrm{C}(\mathrm{g})\)
If p being the total pressure, \({\mathrm{K}}_{\mathrm{p}}\) is the pressure equilibrium constant and \(\alpha\) is the degree of dissociation, then which of the following is true at equilibrium ?

[JEE Main 2025, 2 Apr (Shift 2)]

a

If \(\mathrm{p}\) value is extremely high compared to \({\mathrm{K}}_{\mathrm{p}},\alpha \approx 1\)

b

When p increases \(\alpha\) decreases

c

If \({\mathrm{k}}_{\mathrm{p}}\) value is extremely high compared to \(\mathrm{p},\alpha\) becomes much less than unity

d

When \(\mathrm{p}\) increases \(\alpha\) increases
