Which one of the following condition will favour maximum formation of the product in the reaction. `A_(2)(g) + B_(2)(g)hArrX_(2)(g) Delta_(r)H = - X` kJ ?

Options

A. Low temperature and high pressure
B. Low temperature and low pressure
C. High temperature and low pressure
D. High temperature and high pressure

Answer

A

Explanation

`A_2(g)+B_2(g) harr X_2(g), DeltaH= -X kJ`
On increasing pressure, equilibrium shifts in a direction where pressure decreases i.e. forward direction.
On decreasing temperature, equilibrium shifts in forward direction as it is exothermic direction.
So, high pressure and low temperature favours maximum formation of product.
