Equilibrium Question 635
Question: When 3 mole of A and 1 mole of B are mixed in 1 litre vessel the following reaction takes place $ {A_{(g)}}+{B_{(g)}} $ ⇌ $ 2{C_{(g)}} $ . 1.5 moles of C are formed. The equilibrium constant for the reaction is [MP PMT 2000]
Options:
A) 0.12
B) 0.25
C) 0.50
D) 4.0
Show Answer
Answer:
Correct Answer: D
Solution:
$ \underset{(3-0.75)}{\mathop{A}},+\underset{(1-0.75)}{\mathop{B}},\to \underset{1.5}{\mathop{2C}}, $
$ K=\frac{{{[C]}^{2}}}{[A][B]}=\frac{{{(1.5)}^{2}}}{2.25\times 0.25}=\frac{2.25}{2.25\times 0.25}=4.0 $ .
