Which of the following reactions will get affected by increasing the pressure? Also, mention whether the change will cause the reaction to go into forward or backward direction.

(I) COCl2 (g) ⇌ CO (g) +Cl2 (g)

(II) CH4 (g) +2S2 (g) ⇌ CS2 (g) + 2H2S (g)

(III) CO2 (g) +C (s) ⇌ 2CO (g)

(IV) 2H(g) +CO  (g) ⇌ CH3OH(g)

(V) CaCO(s) ⇌ CaO (s) + CO2 (g)

(VI) 4NH3 (g) + 5O2 (g) ⇌ 4NO (g) + 6H2O (g)

1 Answer

Solution :-

When pressure is increased:

The reactions given in (i), (iii), (iv), (v), and (vi) will get affected.

Since the number of moles of gaseous reactants is more than that of gaseous products; the reaction given in (iv) will proceed in the forward direction

Since the number of moles of gaseous reactants is less than that of gaseous products, the reactions are given in (i), (iii), (v), and (vi) will shift in the backward direction
