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
