Chemical and Ionic Equilibrium 1 Question 25
26. Pure ammonia is placed in a vessel at a temperature where its dissociation constant $(\alpha)$ is appreciable. At equilibrium,
$$ \mathrm{N}{2}+3 \mathrm{H}{2} \rightleftharpoons 2 \mathrm{NH}_{3} $$
$(1984,1 \mathrm{M})$
(a) $K_{p}$ does not change significantly with pressure
(b) $\alpha$ does not change with pressure
(c) concentration of $\mathrm{NH}_{3}$ does not change with pressure
(d) concentration of hydrogen is less than that of nitrogen
Show Answer
Solution:
- $K_{p}$ for a given reversible reaction depends only on temperature.
