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 1

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

#5C(s) + 2SO_2(g) rarr CS_2(g) +4CO(g)#

#"Moles of sulfur dioxide"=(450xx10^3*g)/(64.07*g*mol^-1)=7023.6*mol#

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

#82%xx7023.6*molxx1/2xx76.14*g*mol^-1-=219.2*kg# #CS_2#.

The reaction turns on the stoichiometry. 1 equiv #CS_2# derives from 2 equiv sulfur dioxide..........this is the reason for multiplying the quantity by #1/2#.

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

Approximately 219.25 kg of CS2 can be produced from 450 kg of waste SO2 with an excess of coke, given an SO2 conversion rate of 82%.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
