Question

The change in pressure will not affect the equilibrium constant for : (A)  N2 + 3H2 leftharpoons 2NH3  (B) PCl5 leftharpoons PCl3 + Cl2  (C) H2 + I2 leftharpoons 2HI  (D) all of the above

According to Le Chatlier principle, the change in pressure will not affect the equilibrium of those reactions that contains no difference in the no. of moles of product and reactants.

H_{2} + I_{2} ⇌ 2 H I

no. of moles of product

= 2

no. of moles of reactant

= 1 + 1 = 2

Total change

= 2 - 2 = 0

Q. The change in pressure will not affect the equilibrium constant for :

$N_{2} + 3 H_{2} ⇌ 2 N H_{3}$

$PC l_{5} ⇌ PC l_{3} + C l_{2}$

$H_{2} + I_{2} ⇌ 2 H I$

all of the above

Q. The change in pressure will not affect the equilibrium constant for :

N2​+3H2​⇌2NH3​

PCl5​⇌PCl3​+Cl2​

H2​+I2​⇌2HI

all of the above

According to Le Chatlier principle, the change in pressure will not affect the equilibrium of those reactions that contains no difference in the no. of moles of product and reactants. H2​+I2​⇌2HI no. of moles of product =2 no. of moles of reactant =1+1=2 Total change =2−2=0

$N_{2} + 3 H_{2} ⇌ 2 N H_{3}$

$PC l_{5} ⇌ PC l_{3} + C l_{2}$

$H_{2} + I_{2} ⇌ 2 H I$
