Medium$0.6 \ mol$ of $NH_3$ in a reaction vessel of $2 \ dm^3$ capacity was brought to equilibrium. The vessel was then found to contain $0.15 \ mol$ of $H_2$ formed by the reaction $2NH_{3(g)} \rightleftharpoons N_{2(g)} + 3H_{2(g)}$. Which of the following statements is true?
- A$0.15 \ mol$ of the original $NH_3$ had dissociated at equilibrium
- B$0.55 \ mol$ of ammonia is left in the vessel
- CAt equilibrium the vessel contained $0.45 \ mol$ of $N_2$
- DThe concentration of $NH_3$ at equilibrium is $0.25 \ mol \ dm^{-3}$

View SolutionIn a $10 \ L$ vessel,$SO_3, SO_2$,and $O_2$ gases are present at a definite temperature with $K_c = 100$. For the reaction $2SO_{2(g)} + O_{2(g)} \rightleftharpoons 2SO_{3(g)}$,if $SO_3$ and $SO_2$ are present in the same number of moles at equilibrium,find the moles of $O_2$. If $SO_3$ is double the moles of $SO_2$,what is the number of moles of $O_2$?
