SO3 can be produced from 7.2 g O2 and excess S

SO3 can be produced from 7.2 g O2 and excess S

 

 

For the reaction 2S(g) + 3O2(g) → 2SO3(g)

how many moles of SO3 can be produced from 7.2 g O2 and excess S?

 

---------------------------------------------------

 

7.2 g / (32.00 g/mol) = 0.225 mol O2

S가 과량이므로,

O2가 한계 반응물.

( 참고: 한계 반응물 https://ywpop.tistory.com/3318 )

 

 

 

O2 : SO3 = 3 : 2 = 0.225 mol : ? mol

? = 2 × 0.225 / 3 = 0.150 mol SO3
