Select whether there is no work done by the system, work done by the system or work done by the surroundings for each system described below:
a. h2o (l) ⟶ h2o (g) δh = 44.0 kj/mol b. 2 no (g) + o2 (g) ⟶ 2 no2(g) δh = -114.1 kj/mol c. cl (g) + o3 (g) ⟶ clo(g) + o2(g) δh = -163 kj/mol d. caco3 (s) ⟶ cao (s) + co2(g) δh = 110.1 kj/mol e. 4 nh3(g) + 5 o2(g) ⟶ 4 no (g) + 6 h2o(l) δh = -906 kj/mol
