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

Answer

C

Explanation

`A_(2)(g) + B_(2)(g) hArr X_(2)(g), DeltaH=-xKJ`
On increasing pressure equilibrium shifts in a direction where pressure decreases i.e. forward direction.
On decreasing temperature , equilibrium shifts in exothermic direction i.e., forward direction. So high pressure and low temperature favours maximum formation of product.
