In the reaction, N2 + 3H2 → 2NH3 the ratio of volumes of nitrogen, hydrogen and ammonia is 1: 3: 2. These figures illustrate the law of:
(A) constant proportions
(B) ***-Lussac
(C) multiple proportions
(D) reciprocal proportions
(B) -Lussac*
Explanation:
The above ratio of 1 : 3 : 2 illustrates the ***-Lussac law of combining volume.
