1.	Calculate the change of entropy ΔrS∘m at 298 K for the reaction in which urea is formed from NH3 and CO2. The standard entropy of NH2CONH2 is 174.0 JK−1mol−1. For NH3, CO2 and H2O it is 192.3, 213 and 69.9JK−1
Answer» Calculate the change of entropy $Δ_{r} S_{m}^{\circ}$ at 298 K for the reaction in which urea is formed from $N H_{3}$ and $C O_{2}$ . The standard entropy of $N H_{2} C O N H_{2}$ is 174.0 $J K^{- 1} m o l^{- 1}$ . For $N H_{3}$ , $C O_{2}$ and $H_{2} O$ it is 192.3, 213 and 69.9 $J K^{- 1}$
