How much heat is released in the condensation of 1.5 mol of steam at 100°C to water at 100°C if ΔHcond for water = –40.7 kJ/mol?

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)

Can someone me with questions 12 and 13 plz.
