Question

Ethylene (C2H4) reacts with hydrogen toform ethane (C2H6) C2H4(g) + H2(g) -----C2H6(g) +heat How would you regulate the temps of this equilibrium in orderto accomplish each of the following? A. increase yeild of ethane B. decrease the concentration of ethylene C. increase the amount of hydrogen in the system Ethylene (C2H4) reacts with hydrogen toform ethane (C2H6) C2H4(g) + H2(g) -----C2H6(g) +heat How would you regulate the temps of this equilibrium in orderto accomplish each of the following? A. increase yeild of ethane B. decrease the concentration of ethylene C. increase the amount of hydrogen in the system

Explanation / Answer

A. increase yeild of ethane
increase the product ---> favors the product ---> decreasethe temperature
B. decrease the concentration of ethylene
decrease the reactant ---> favors the product ---> decreasethe temperature
C. increase the amount of hydrogen in the system
increase the reatant ---> favors the reactant ---> increasethe temperature
