Chapter 22, Problem 22.25E
Interpretation Introduction
Interpretation:
The expected effect on change in pressure as the temperature increases is to be stated. The corresponding effect agrees with the equation for the change in pressure across the interface of the droplet, bubble and the behavior of
Concept introduction:
Surface tension is the tension of a liquid surface that causes due to the attraction of liquid particles in the liquid surface by the liquid particle present in the bulk of the liquid. The surface tension tries to attain a minimum surface area. The formula of surface tension is given by the expression shown below.

Consider the greenhouse gases, CF2Cl2 and CH2CF2. These have the following properties:
CF2Cl2: ΔGfo = -491 kJ/mol, atmospheric lifetime = 102 years, ozone depletion potential = 0.73
CH2CF2: ΔGfo = -451 kJ/mol, atmospheric lifetime = 5.4 years, ozone depletion potential = 0.0
Clearly, CH2CF2 is less hazardous in the atmosphere than CF2Cl2. Is it thermodynamically favorable under standard conditions to react CF2Cl2 with H2 gas to convert it to CH2CF2? (ΔGfo = 0 for H2 and Cl2)
CF2Cl2 + H2 ⇌ CH2CF2 + Cl2
Justify your answer and calculate the equilibrium constant for this reaction.

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_forward
