Question

Equal no. of moles of SO2, and 02,reacts to form
SO3. Which one is the limiting reactant.
(1) 02
(2) SO,
(3) SO;
(4) None​

Answer 1

Answer:

SO2

Explanation:

SO2 + O2 ----> SO3

2SO2 + O2 ---> 2SO3 (Balanced equation)

We can see, 2 Moles of SO2 reacts with 1 Mole of Oxygen to form 2 Moles of SO3.

SO2 is required twice more than O2.

So SO2 is the limiting reagent and O2 is the excess reagent.
