Equilibrium Question 616
Question: In a chemical equilibrium $ A+B $ ⇌ $ C+D $ , when one mole each of the two reactants are mixed, 0.6 mole each of the products are formed. The equilibrium constant calculated is [CBSE PMT 1989]
Options:
A) 1
B) 0.36
C) 2.25
D) 4/9
Show Answer
Answer:
Correct Answer: C
Solution:
A+ B ⇌C+ D Initial 1 1 0 0 remaining at equilibrium 0.4 0.4 0.6 0.6 $ K=\frac{[C][D]}{[A][B]}=\frac{0.6\times 0.6}{0.4\times 0.4}=\frac{36}{16}=2.25 $ .
