Correct Answer: 1.92 - 1.93
Solution and Explanation
The balanced chemical reaction is:
C2H4 + H2 → C2H6 (90% catalytic conversion)
Step 1: Determine the moles of reactants
- Molar mass of C2H4 = 28 g/mol
- Molar mass of H2 = 2 g/mol
- Moles of C2H4 = (2000 g)/(28 g/mol) ≈ 71.43 mol
- Moles of H2 = (2000 g)/(2 g/mol) = 1000 mol
Step 2: Identify the limiting reactant
- For full conversion, 71.43 mol of C2H4 requires 71.43 mol of H2.
- C2H4 is the limiting reactant since all of it reacts first.
Step 3: Calculate the moles of C2H6 produced
- Moles of C2H6 = 71.43 mol (90% conversion) = 71.43 * 0.90 ≈ 64.29 mol
Step 4: Calculate the mass of C2H6 produced
- Molar mass of C2H6 = 30 g/mol
- Mass of C2H6 = 64.29 mol * 30 g/mol = 1928.57 g = 1.93 kg
The mass of ethane produced is 1.93 kg.
