Concept explainers

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that …

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energ…

Chapter 10, Problem 10.102QP

Referring to Table 9.4, explain why the bond enthalpy for Cl₂ is greater than that for F₂. (Hint: The bond lengths of F₂ and Cl₂ are 142 pm and 199 pm, respectively.)

Table 9.4 Some Bond Enthalpies of Diatomic Molecules* and Average Bond Enthalpies for Bonds in Polyatomic Molecules

Chapter 10, Problem 10.102QP, Referring to Table 9.4, explain why the bond enthalpy for Cl2 is greater than that for F2. (Hint:

*Bond enthalpies for diatomic molecules (in color) have more significant figures than bond enthalpies for bonds in polyatomic molecules, because the bond enthalpies of diatomic molecules are directly measurable quantities and not averaged over many compounds.

^† The C═O bond enthalpy in CO₂ is 799 kJ/mol.

The table below includes the bond enthalpy (the energy required to separate the diatomic molecule into its atoms) and the bond length for each diatomic molecule. Diatomic Molecule Bond Enthalpy (kJ/mol) Bond Length (pm) Cl2 243 199 O2 498 121 N2 945 110 Identify the observed trend between bond enthalpy and number of shared electrons: as the number of electrons shared between two atoms increases, the bond enthalpy ( increases / decreases / remains unchanged ). Identify the observed trend between bond length and number of shared electrons: as the number of electrons shared between two atoms increases, the bond length ( increases / decreases / remains unchanged ).

A scientist studies the bond energies of different compounds containing nitrogen (N). The scientist observes that the N–N bonds in one group of compounds have a bond energy of 209 kJ/mol, while the N–N bonds in another group of compounds have a bond energy of 418 kJ/mol. In one or two sentences, postulate a reason for this difference.

In chemical reactions, heat is converted into chemical energy (the potential energy stored in chemical bonds) or vice versa. Bond energy is the energy required to break one mole of the bond in the gas phase. Since it takes energy to break a bond, bond energies are always positive. Conversely, energy is released when bonds are formed. Thus, the enthalpy change for a reaction can be approximated from Part A Calculate the bond energy per mole for breaking all the bonds in methane, CH4.
