To an open beaker containing 500ml of water at 298k, 20g of sodium metal is added. the reaction proceeds quite rigorously but ultimately comes to rest after consuming all of the sodium metal and thermally reequilibrating with the surroundings. The Na metal reacts with the water according to the reaction:
2Na(s)+2H20(l)-->2NaOH(aq)+H2(g) Delta H (298k) = -368.6 kJ
determine value of Qp, Delta H and delta U
