Question- Urea ((NH2)2CO) can be formed from ammonia and carbon dioxide as shown in the following reaction. The ?H° value for this synthesis is -134.0 kJ. Calculate the ?H°ffor urea.
2NH3(g) + CO2(g) ? (NH2)2CO(s) + H2O(l)
Calculate ?G° for the synthesis of urea under standard conditions (298 K and 1 atm).
The ?S° value for urea the synthesis reaction above is -424.0 J/K. Calculate S° for urea.
My main issue is that I think I have to have a balanced reaction in order to do the calculations.
