Question

For the reaction $CO ( g )+\left(\frac{1}{2}\right) O _{2}( g ) \longrightarrow CO _{2}( g ), K _{ p } / K _{ c }$ is

• A. $RT$
• B. $(RT)^{-1}$
• C. $(RT)^{-1/2}$
• D. $(RT)^{1/2}$

Answer 1

The Correct Option is C

$K_{p}=K_{c}(R T)^{\Delta n} ; \Delta n=1-\left(1+\frac{1}{2}\right)$
$=1-\frac{3}{2}=-\frac{1}{2}$
$\therefore \frac{K_{p}}{K_{c}}=(R T)^{-1 / 2}$
