Hi everyone. This time I need help with finding the Gibbs Free Energy of this chemical reaction: CaC2(s)+2H2O(l) --> C2H2 + Ca(OH)2
The question says to use the standard-state free energies of formation,![[IMG]](proxy.php?image=http%3A%2F%2Fwww.crazyengineers.com%2Fcommunity%2Fgraphics%2Fdelta.gif&hash=eac8ee492e5e84c755b6e91264bc8c99)
Gfo for finding the Gibbs free energy to prove that even if Acetylene cant be synthesized from an element,we can get Acetylene from this reaction.
StaNdard free energies of formation for each compound:
CaC2=-64.9
H2O=-237.2
C2H2=209.2
Ca(OH)2=-898.6
The answer is -150.1 kJ
