For which of the following reactions, (K\_{p}=K\_{c} ?) | Chemistry | SolveeIt

For which of the following reactions, $K_{p}=K_{c} ?$

$N _{2}+3 H _{2} 2 NH _{3}$

$N _{2}+ O _{2} 2 NO$

$PCl _{5} PCl _{3}+ Cl _{2}$

$2 SO _{3} 2 SO _{2}+ O _{2}$

Answer

$N _{2}+ O _{2} 2 NO$

Explanation

$K_{p}=K_{c}(R T)^{\Delta n}$
For the reaction: $N_{2}+O_{2} 2 N O$
$\Delta n=2-2=0$
$\therefore K_{p}=K_{c}(R T)^{0}$
$K_{p}=K_{c}$
