Equilibrium Question 584
Question: Value of $ K_{p} $ in the reaction $ MgC{O_{3(s)}} $ ⇌ $ Mg{O_{(s)}} $ $ +,C{O_{2(g)}} $ is [CBSE PMT 2000; RPMT 2002]
Options:
A) $ K_{P}=P_CO_2 $
B) $ K_{P}=Pco_2\times \frac{Pco_2\times P_{MgO}}{{P _{MgCO_3}}} $
C) $ K _{P}=\frac{Pco_2\times P _{MgO}}{{P _{MgCO_3}}} $
D) $ K_{P}=\frac{{P _{MgCO_3}}}{{P _{CO_2}}\times P _{MgO}} $
Show Answer
Answer:
Correct Answer: A
Solution:
In this reaction gaseous molecule count $ MgCO_3\to Mg{O_{(s)}}+C{O_{2(g)}} $
$ K_{p}={P _{CO_2}} $
