Equilibrium Question 632
Question: At 3000 K the equilibrium pressures of CO2, CO and O2 are 0.6,0.4 and 0.2 atmospheres respectively. $ K_{p} $ for the reaction, $ 2CO_2 $ ⇌ $ 2CO+O_2 $ is [JIPMER 1999]
Options:
A) 0.089
B) 0.0533
C) 0.133
D) 0.177
Show Answer
Answer:
Correct Answer: A
Solution:
$ K_{p}=\frac{{{[P_{CO}]}^{2}}[{P_{O_2}}]}{{{[{P_{CO_2}}]}^{2}}}=\frac{{{[0.4]}^{2}}\times [0.2]}{{{[0.6]}^{2}}}=0.0888 $ .
