Problem 5.42

Without referring to tables, predict which of the following has the higher enthalpy in each case:

(a) \(1 \mathrm{~mol} \mathrm{} \mathrm{CO}_{2}(s)\) or \(1 \mathrm{~mol} \mathrm{CO} 2(g)\) at the same temperature,

(b) \(2 \mathrm{~mol}\) of hydrogen atoms or \(1 \mathrm{~mol}\) of \(\mathrm{H}_{2}\),

(c) \(1 \mathrm{~mol} \mathrm{H}_{2}(g)\) and \(0.5 \mathrm{~mol} \mathrm{O}{ }_{2}(g)\) at \(25^{\circ} \mathrm{C}\) or \(1 \mathrm{~mol} \mathrm{} \mathrm{H}_{2} \mathrm{O}(g)\) at \(25^{\circ} \mathrm{C\),

(d) \(1 \mathrm{~mol} \mathrm{~N}{ }_{2}(g)\) at \(100^{\circ} \mathrm{C}\) or \(1 \mathrm{~mol} \mathrm{~N}_{2}(g)\) at \(300^{\circ} \mathrm{C}\).

1 mol CO2(s)

1 mol CO2(g)

1 mol H2

1 mol H2(g)

 0.5 mol O2(g)

1 mol H2O(g)

1 mol N2(g)

100^{\circ} C

300^{\circ} C

Step-by-Step Solution:

Step 1 of 5) The atomic radii in Figure 7.7 allows us to estimate bond lengths in molecules. For example, the bonding atomic radii for C and Cl are 0.76 Å and 1.02 Å, respectively. In CCl4 the measured length of the C¬Cl bond is 1.77 Å, very close to the sum 10.76 + 1.02 A ° 2 of the bonding atomic radii of Cl and C.Within each group, bonding atomic radius tends to increase from top to bottom. This trend results primarily from the increase in the principal quantum number 1n2 of the outer electrons. As we go down a column, the outer electrons have a greater probability of being farther from the nucleus, causing the atomic radius to increase.
