Equilibrium Question 669
Question: What is the equilibrium constant for the reaction’ $ {P_{4(s)}}+5{O_{2(g)}} \leftrightharpoons P_4{O_{10(s)}} $
Options:
A) $ K_{C}=\frac{1}{{{[ O_2 ]}^{5}}} $
B) $ K_{C}=\frac{[ P_4O_{10} ]}{5[ P_4 ][ O_2 ]} $
C) $ K_{C}={{[ O_2 ]}^{5}} $
D) $ K_{C}=\frac{[ P_4O_{10} ]}{5[ P_4 ]{{[ O_2 ]}^{5}}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Concentration of solid species is supposed to be unity.
$ \therefore K_{C}=\frac{1}{{{[O_2]}^{5}}} $
