A) \[{{K}_{p}}={{K}_{c}}\]
B) \[{{K}_{p}}<{{K}_{c}}\]
C) \[{{K}_{p}}>{{K}_{c}}\]
D) Pressure is required to predict the correlation
Correct Answer: B
Solution :
Key Idea: \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] Find the value of\[\Delta n\]from the given equation to find relation between\[{{K}_{p}}\]and\[{{K}_{c}}\] \[{{N}_{2}}(g)+3{{H}_{2}}(g)2N{{H}_{3}}(g)\] \[\Delta n={{n}_{p}}-{{n}_{r}}\] \[=2-4\] \[=-2\] \[\therefore \] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{-2}}\] Or \[{{K}_{p}}=\frac{{{K}_{c}}}{{{(RT)}^{2}}}\] \[{{K}_{p}}<{{K}_{c}}\]
