Rate of formation of \(\sf SO_3\) according to the reaction \(\sf 2SO_2+O_2 \rightarrow 2SO_3\) is \(\sf 1.6 \times 10^{-3}~Kg.min^{-1}\). Rate at which \(\sf SO_2\) reacts is?

According to me it should be either \(\sf 1.6 \times 10^{-3} or ~8 \times 10^{-4}\)

\(\sf \Large \frac{1}{2}-\frac{d[SO_2]}{dt}=\frac{1}{2}\frac{d[SO_3]}{dt} \), isn't that correct?
Abhisar
  • Abhisar
Umm...but the answer key given says it should be \(\sf 1.28 \times 10^{-3}\)

I dunno how :O

\[\frac{- d[SO _{2}] }{ dt }= \frac{ 1 }{ 2 }\frac{ d[SO _{3}] }{ dt }\] right? So I think u are correct ! How? Isn't the rate of formation of SO3 equal to rate of disappearance of SO2 ?
Rushwr
  • Rushwr
wait what's the equation ! I think I got i wrong!

\(\sf 2SO_2+O_2 \rightarrow 2SO_3\)

I have no idea !!!!!!!!!! Still wondering how it can be !!!!!!!!!!!!!!!!!!!!!

  • Abhisar
Ok, Thnks. I think the answer key is incorrect!
Abhisar
  • Abhisar
But can you reconfirm what the rate equation will be ? Wil it be \(\sf \Large \frac{1}{2}\frac{-d[SO_2]}{dt}=\frac{1}{2}\frac{d[SO_3]}{dt} \) or the one you wrote?
Rushwr
  • Rushwr
this one is correct I agree ! But The answer won't be the same isn't it !
Abhisar
  • Abhisar
If they are asking rate of disappearance of SO2 then it would be same as that of SO3 but if they mean the rate of reaction it should be half i.e. 8 X !0^-4. that's what I think.
Rushwr
  • Rushwr
I think it would have the same value. 1.6
Abhisar
  • Abhisar
Yeah, cz they are asking the rate at which SO2 reacts which sounds more like its individual rate. All right thanks a bunch for your time. really appreciate it c;
