Question

the reactor initially contained 1 mole of ethane and 0.5 moles each of ethylene and ydrogen. calculate the contents of each reactor

Answer 1

The contents of the reactor at equilibrium are 0 moles of ethane, 0.5 moles of ethylene, and 0.5 moles of hydrogen.

Step-by-step explanation:

The initial contents of the reactor are:

• 1 mole of ethane
• 0.5 moles of ethylene
• 0.5 moles of hydrogen

Given the balanced chemical equation:

C2H6 + C2H4 + 3H2 -> 2C2H6

We can see that for every 1 mole of ethane reacted, 1 mole of ethylene and 3 moles of hydrogen are consumed. Therefore, at equilibrium, the contents of the reactor will be:

• 0 moles of ethane
• 0.5 moles of ethylene
• 0.5 moles of hydrogen
