Corrections to Siberberg 2 nd Ed. Chapter 6, Section 6 Changes to Chapter 6, Section 6 The middle of page 203 to the end of page 203 should be replaced by the following (note that changes and additions are underlined): • For a pure gas (element or compound) , the standard state is 1 atm * with the gas behaving ideally. • For a substance in aqueous solution , the standard state is 1 M concentration. • For a pure liquid or solid (element or compound), the standard state is 1 atm. In this text, the temperature is usually 25°C (298 K) , but the above definitions of standard states do not require that the temperature be 25°C . We use a degree sign to indicate these standard states. In other words, when the heat of reaction, H rxn , has been measured with all the reactants and products in their standard states, it is referred to as the standard heat of reaction, rxn .
