COMEDK · Chemistry · 7. Chemical Equilibrium
In which one of the following equilibria, pressure has no effect
- A \(\mathrm{PCl}_{5} \rightleftharpoons \mathrm{PCl}_{3}+\mathrm{Cl}_{2}\)
- B \(2 \mathrm{NH}_{3} \longrightarrow \mathrm{N}_{2}+3 \mathrm{H}_{2}\)
- C \(2 \mathrm{SO}_{2}+\mathrm{O}_{2} \rightleftharpoons 2 \mathrm{SO}_{3}\)
- D \(\mathrm{N}_{2}+\mathrm{O}_{2} \rightleftharpoons 2 \mathrm{NO}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{N}_{2}+\mathrm{O}_{2} \rightleftharpoons 2 \mathrm{NO}\)
Step-by-step Solution
Detailed explanation
When \(\Delta n_{g}\) i.e. difference in gaseous moles of product and reactant is zero, then pressure has no effect and it is equilibrium point for reaction.…
