Question

0.5 mol each of H2S and SO2 are mixed together in a reaction flask in which the

following reaction takes place : [2]

2H2S (g) + SO2 (g) → 2H2O (l) + 3S (s)

Calculate the number of moles of sulphur formed.​

Answer 1

Answer:

So 2 moles of H2S reacts with 1 mole of SO2. We have 0.5 moles of H2S and SO2. Then 0.5 moles of H2S reacts with 1/4 moles of SO2, and forms 2/4 =1/2 moles of water and 3/4 moles of Sulfur. So answer = 3/4 moles.
