Some Basic Concepts of Chemistry
2nd option is correct 2mole so2 reacts with 1 mole o2 therefore, 1 mole so2 will react with 0.5 mole o2 this means,o2 is excess reagent and so2 is limiting 2 mole so2 form 2 mole so3 therefore 1 mole so2 will form 1 mole so3..
ThANK YOU
But if o2 is limiting reagent it should be consumed
Ques14 PlS TEll this question
Only 1 mole of so3will be produced
Please answer this question
32g of so2 reacts with 48g if o2 to produce so3 find limiting reagent in manufacture of so3
In this reaction 2so2 +O2 ------> 2SO3 when 1 mole of so2 and 1 mole of O2 are made to react to completion
