Enter its chemical formula: 2so, O, 2 of which reactant are there the least initial moles? Enter its chemical formula

Explanation / Answer

1)

number of molecules of SO2 = 6

number of molecules of O2 = 7

Clearly O2 is more than SO2

Answer: O2

2)

Answer: SO2

3)

The reaction is:

2 SO2 + O2 —> 2 SO3

for 1 mol of O2 we need 2 mol of SO2

So,

for 1 molecule of O2 we need 2 molecule of SO2

we have less SO2

So, SO2 is limiting reagent

Answer: SO2
