Question 1

Calculate the amount of work done against an atmospheric pressure of 1.00 atm when 500.0 g of zinc dissolves in excess acid at 30.0°C.
         Zn(s) + 2H+(aq) → Zn2+(aq) + H2(g)
◦ w = +22.4 kJ
◦ w = +24.9 kJ
◦ w =  0
◦ w = –2.52 kJ
◦ w = –19.3 kJ

Question 2

Calculate the amount of work done, in joules, when 2.5 mole of H2O vaporizes at 1.0 atm and 25°C. Assume the volume of liquid H2O is negligible compared to that of vapor.  (1 L·atm = 101.3 J)
◦ 61.1 J
◦ 518 J
◦ 5.66 kJ
◦ 6.19 kJ
◦ 6,190 kJ
