For the reaction, N2 + 3H2 -> 2NH3, d NH dt = 2 x 10–4 mol L–1 s–1, the value of d H dt would be: (AIPMT 2009)
A.4 × l0–4 mol L–l s–l
B.6 × l0–4 mol L–l s–l
C.1 × l0–4 mol L–l s–l
D.3 × l0–4 mol L–l s–l✓ Correct
Explanation
1/3 × rate of disappearance of H2 =1/2 × rate of formation of NH3. 2 3 1 1 3 2 d H d NH dt dt 2 3 4 4 1 1 3 3 2 10 2 2 3 10 d H d NH dt dt mol L s >> xx x
