Which of the following will favour the formation of `NH_3` by Haber's process ?

Options

A. increase of temperature
B. increases of pressure
C. addition of catalyst
D. addition of a promoter

Explanation

To determine which conditions will favor the formation of ammonia (NH₃) by Haber’s process, we need to analyze the reaction and the factors that affect chemical equilibrium. The Haber process can be represented by the following equation:

\[ N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g) \]

### Step 1: Understand the Reaction
The reaction involves nitrogen gas (N₂) and hydrogen gas (H₂) reacting to form ammonia (NH₃). The formation of ammonia is an exothermic reaction, meaning it releases heat.

### Step 2: Apply Le Chatelier's Principle
