Question

In which of the following reaction, the value of Kp will be equal to Kc? (A) H2 + I2 leftharpoons 2HI (B) PCl5 leftharpoons PCl3 + Cl2 (C) 2NH3 leftharpoons N2 + 3H2 (D) 2SO2 + O2 leftharpoons 2SO3

np = nf then Kp = Kc where np = number of moles of product nr - number of moles of reactant

Q. In which of the following reaction, the value of $K_{p}$ will be equal to $K_{c}$ ?

$H_{2} + I_{2} ⇌ 2 H I$

$PC l_{5} ⇌ PC l_{3} + C l_{2}$

$2 N H_{3} ⇌ N_{2} + 3 H_{2}$

$2 S O_{2} + O_{2} ⇌ 2 S O_{3}$

$n_{p} = n_{f}$ then $K_{p} = K_{c}$
where $n_{p}$ = number of moles of product
$n_{r}$ - number of moles of reactant
