Equilibrium Question 610
Question: Partial pressures of A, B, C and D on the basis of gaseous system $ A+2B $ ⇌ $ C+3D $ are A = 0.20; B = 0.10; C = 0.30 and D = 0.50 atm. The numerical value of equilibrium constant is [CPMT 1987]
Options:
A) 11.25
B) 18.75
C) 5
D) 3.75
Show Answer
Answer:
Correct Answer: B
Solution:
A + 2B ⇌C + 3D $ K=\frac{[pC]{{[pD]}^{3}}}{[pA]{{[pB]}^{2}}}=\frac{0.30\times 0.50\times 0.50\times 0.50}{0.20\times 0.10\times 0.10}=18.75 $
