Question

In an exothermic equilibrium A + 3B leftharpoons AB3 all the reactants and product are in gaseous state. The formation of AB3 is favoured at (A) Low temperature and low pressure (B) Low temperature and high pressure (C) High temperature and high pressure (D) High temperature and low pressure

Tardigrade Admin · Accepted Answer

The given reaction is exothermic (Δ H<0) and accompanied by decrease in the number of moles. Hence, it will be favoured by low temperature and high pressure.

Q. In an exothermic equilibrium
$A + 3 B ⇌ A B_{3}$
all the reactants and product are in gaseous state. The formation of $A B_{3}$ is favoured at

Low temperature and low pressure

Low temperature and high pressure

High temperature and high pressure

High temperature and low pressure

High temperature and very low pressure

The given reaction is exothermic $(Δ H < 0)$ and accompanied by decrease in the number of moles. Hence, it will be favoured by low temperature and high pressure.
