Answer:
801kg of adiponitrile would be produced
Explanation:
The reaction of HCN and butadiene is:
2HCN + Butadiene → Adiponitrile.
<em>Where 2 moles of HCN reacts per mole of butadiene to produce 1 mole of adiponitrile</em>
<em> </em>
The maximum amount of adiponitrile produced depends of the <em>limiting reactant. </em>To find limiting reactant we need to find moles of butadiene and HCN that react:
<em>Moles butadiene - Molar mass: 54g/mol-:</em>
450kg = 450000g * (1mol / 54g) = 8333 moles of butadiene
<em>Moles HCN -Molar mass: 27g/mol-:</em>
400kg = 400000g * (1mol / 27g) = 14815 moles HCN
Based on the chemical equation, for a complete reaction of 14815 moles of HCN are required:
14815 moles HCN * (1mol butadiene / 2 moles HCN) = 7407 moles of butadiente are required.
As there are 8333 moles of butadiene, <em>HCN is limiting reactant.</em>
And maximum moles of adiponitrile that can be obtained are:
14815 moles HCN * (1mol adiponitrile / 2 moles HCN) =
7407 moles of adiponitrile is the maximum amount that can be obtained
In grams -Molar mass: 108.14g/mol-:
7407 moles Adiponitrile * (108.14g/mol) = 801037g of adiponitrile:
<h3>801kg of adiponitrile would be produced</h3>
