Question 1

The values of ΔH°f for the three states of benzene are approximately -22 kcal/mol, -11 kcal/mol, and

Which is the value for solid benzene?
◦ 20 kcal/mol
◦ -11 kcal/mol
◦ -22 kcal/mol
◦ cannot be determined without additional information

Question 2

Which equation represents the reaction whose ΔH, represents the standard enthalpy of formation of CHCl3(l) at 25°C? (i.e., for which is ΔH = ΔH°f of CHCl3)
◦ C(s) + 1/2 H2(g) + 3/2 Cl2(g) → CHCl3(l)
◦ 2 C(s) + H2(g) + 3 Cl2(g) → 2 CHCl3(l)
◦ C(s) + H(g) + 3 Cl(g) → CHCl3(l)
◦ CHCl3(l) → C(s) + H(g) + 3 Cl(g)
