# Carbon disulphide 'CS2' . Can be made from by product SO2. The overall reaction is 5C + 2SO2 -------> CS2 + 4CO How much CS2 can be produced from 450kg of waste SO2 with excess of coke if the SO2 conversion is 82%?

#### Answer:

You have the stoichiometric equation.......

#### Explanation:

$5 C \left(s\right) + 2 S {O}_{2} \left(g\right) \rightarrow C {S}_{2} \left(g\right) + 4 C O \left(g\right)$

$\text{Moles of sulfur dioxide} = \frac{450 \times {10}^{3} \cdot g}{64.07 \cdot g \cdot m o {l}^{-} 1} = 7023.6 \cdot m o l$

And thus, factoring in the yield AND the stoichiometry......we gets.....

82%xx7023.6*molxx1/2xx76.14*g*mol^-1-=219.2*kg $C {S}_{2}$.

The reaction turns on the stoichiometry. 1 equiv $C {S}_{2}$ derives from 2 equiv sulfur dioxide..........this is the reason for multiplying the quantity by $\frac{1}{2}$.

This is not a reaction I would like to do. It must mucho pen and ink!
