A mixture of one part nitrogen and three parts hydrogen is heated to a temperature of 773 Kelvin. Use the law of mass action to calculate the fraction of nitrogen that is converted (atom to atom) to ammonia if the final total pressure is 400 bar. As alwyas, use 1 bar for the reference pressure...

1223/18 = 67.97J/K i think that should be the right answer. thanks a lot, i really appreciate it.

1)Latent heat of fusion = 334,000J/kg 334000/273 = 1223 2)63.3-1223 = -1160J/K? is it possible? did i make a mistake somewhere? 3)how do you convert moles to kg? thanks

Thank you very much Mapes here is a little calculation i did, can you please check if it's right latent heat = 334(J/kg) Temperature =273(K) L/T = 1.22 and so the entropy of ice would be 69.91/1.22? or would it be 69.91X1.22?

The Specific Entropy of Water is 69.9J/K. What about ice? i did a search on the internet but couldn't find anything Please help
