Chapter 9, Problem 9.11P

Interpretation Introduction

Interpretation:

The heat of formation of the dried fungus cells is to be calculated.

Concept introduction:

Heat of combustion is the heat released when a substance is combusted in presence of oxygen to yield specific products such as, ${\text{CO}}_2\left(\text{g}\right),{\text{ H}}_2\text{O}\left(\text{l}\right)$ with both the reactants and products being at the standard temperature and pressure or the reference state.

Heat of formation is the change in enthalpy associated with the formation of the compound at the reference temperature and pressure.

Heat of reaction is the change in enthalpy for a process in which stoichiometric amounts of reactants react completely to form products in a single reaction at the reference temperature and pressure.
