Explanation / Answer

Q1.

HRxn = Hproducts - Hreactants

HRxn = 2*H-(NO2) + 3*H-Cl2(g) - ( 2*H-NOCl + 2*H-Cl2O)

HRxn = 2*33.18 + 0- (2*51.71 + 2*80.3) = -167.66 kJ/mol

Q2.

SRxn = Sproducts - Sreactants

SRxn = 2*S-(NO2) + 3*S-Cl2(g) - ( 2*S-NOCl + 2*S-Cl2O)

SRxn = 2*240.06+ 3*223.066 - (2*261.69+ 2*266.21) = 93.518 J/K

Q.3

GRxn = Gproducts - Greactants

GRxn = 2*G-(NO2) + 3*G-Cl2(g) - ( 2*G-NOCl + 2*G-Cl2O)

GRxn = 2*51.31+ 3*0- (2*97.9+ 2*66.08) = -225.34 kJ

Q4.

GRxn = dHRxn - T*dSRxn = -167.66 - 298*93.518 /1000 = -195.52 kJ
