Chapter 16, Problem 48QRT
Interpretation Introduction
Interpretation:
The prediction about the enthalpy change and entropy change has to be done without doing calculations.
Concept Introduction:
The term entropy is used to represent the randomness in a system. When a system moves from an ordered arrangement to a less order arrangement, then the entropy of the system increases.

- Coal is used as a fuel in some electric-generating plants. Coal is a complex material, but for simplicity we may consider it to be a form of carbon. The energy that can be derived from a fuel is sometimes compared with the enthalpy of the combustion reaction: C(s)+O2(g)CO2(g) Calculate the standard enthalpy change for this reaction at 25C. Actually, only a fraction of the heat from this reaction is available to produce electric energy. In electric generating plants, this reaction is used to generate heat for a steam engine, which turns the generator. Basically the steam engine is a type of heat engine in which steam enters the engine at high temperature (Th), work is done, and the steam then exits at a lower temperature (Tl). The maximum fraction, f, of heat available to produce useful energy depends on the difference between these temperatures (expressed in kelvins), f = (Th Tl)/Th. What is the maximum heat energy available for useful work from the combustion of 1.00 mol of C(s) to CO2(g)? (Assume the value of H calculated at 25C for the heat obtained in the generator.) It is possible to consider more efficient ways to obtain useful energy from a fuel. For example, methane can be burned in a fuel cell to generate electricity directly. The maximum useful energy obtained in these cases is the maximum work, which equals the free-energy change. Calculate the standard free-energy change for the combustion of 1.00 mol of C(s) to CO2(g). Compare this value with the maximum obtained with the heat engine described here.arrow_forwardWhich of the following statement is NOT true? The equilibrium constant of a reaction varies with temperature. In most biochemical systems, enthalpy is equivalent to heat. Any deviation from equilibrium prompts a process to restore the system to equilibrium. Free energy changes can be calculated from reactant and product concentrations. If a system maintains a steady state it must have reached equilibrium.arrow_forwardA student determines the value of the equilibrium constant to be 6.41 × 10³ for the following reaction. CO(g)+H,O(0) → CO2(g)+H2(g) Based on this value of Keq: AGO for this reaction is expected to be zero.
