Chapter 17.4, Problem 35SP
Interpretation Introduction

Interpretation: The standard enthalpy change for the reaction is to be found.

Concept introduction: The standard enthalpy of formation is the amount of energy released or consumed when one mole of a substance is formed under standard conditions from its pure elements.

Standard temperature and pressure conditions are 298 K and 1 atm.

The enthalpy of formation for an element in its elemental state or naturally occurring state will always be zero because it takes no energy to form a naturally occurring compound.

Answer to Problem 35SP

  ΔH° for the given reaction Br2(g)Br2(l) is -31kJ/mol

Explanation of Solution

At 298 K and 1 atm, the standard state of bromine is liquid, thus standard enthalpy of formation of Br2(l) is zero.

At 298 K and 1 atm, the standard enthalpy of formation of Br2(g) is 31kJ/mol .

The standard enthalpy changes of the reaction Br2(g)Br2(l) is

  ΔH°=H°fBr2(l)-H°fBr2(g)

  ΔH°= 0kJ/mol-(+31kJ/mol)ΔH°= -31kJ/mol
