Question

In the reaction, $N_2+3H_2\to 2N{H}_3$, the ratio of volumes of nitrogen, hydrogen and ammonia is 1 : 3: 2. These figures illustrate the law of:

• A. constant proportions
• B. Gay-Lussac
• C. multiple proportions
• D. reciprocal proportions

Answer 1

The correct option is B Gay-Lussac

ANS; B

Gay Lussac’s Law of Combining Volumes states that when gases react, they do so in volumes which bear a simple ratio to one another, and to the volume of the product(s) formed if gaseous, provided the temperature and pressure remain constant.
