We see that in the second law of thermodynamics, for any spontaneous process, the entropy of the universe will increase. With a very generalized approach, please try to explain how one spontaneous chemical reaction may increase entropy through its interactions with the environment.

From the thermodynamic data, ΔSsys for the given fuel cell reaction is negative but the reaction is still spontaneous. How can the negative entropy of the system be justified as spontaneous or is it simply violation of second law of thermodynamics? Explain in detail the various factors that can lead to the spontaneity of this reaction. ½ O2(g) + H2(g) → H2O(l)

This is a problem involving an engine with a three thermodynamic process cycle. We have an monatomic ideal gas in a cylinder that can expand and contract. The cylinder can be connected to a hot thermal reservoir at temperature, TH, and also can be connected to a cold reservoir at temperature, TC. We start out at temperture, TH, with Pressure P1 and volume V1. a)Keeping the cylinder connected to the hot reservoir we expand isothermaly to a new volume V2....

***Physical Chemistry Question***** The concept of entropy, and the second law of thermodynamics have often been used (usually misused in reality) to “explain” all kinds of things. It is frequently up to chemists to set the record straight in such cases. One argument which has been used to “disprove” evolution goes something like this: Living beings are more complex than nonliving systems. Furthermore, humans are more biologically complex than lower life forms such as monkeys. Entropy is a measure of...

Subject: Thermodynamics Mechanical Engineering Problem I. For CO2 draw and describe each process in the three graphs (T-v ; P-v; T-s) for a cycle where: Process A-B : Constant pressure for subcooled state A, superheated state B. Process of B-C: isentropic expansion, the state C will have a quality of 90%. Process C-D: constant pressure superheat process, state D superheated to the same temperature as state B. Process D-E: isentropic expansion process, state E saturated steam. Process E-F with isobaric...

Thermodynamics Question A Joule expansion refers to the expansion of a gas from volume V1 to volume V2against no applied pressure, and is sometimes also called a free expansion. There is no work done, because the P of -PdV is zero. By insulating the system, this process can be done adiabatically, so there is no change in heat. For an ideal gas, the adiabatic process is also isothermal, so there is no change in thermodynamic energy, ∆U = 0 (which...

What do you understand by the cogeneration of power and process heat? Explain its thermodynamic advantage? Q2) Consider a regenerative gas-turbine power plant with two stages of compression and two stages of expansion. The overall pressure ratio of the cycle is 9. The air enters each stage of the compressor at 300 K and each stage of the turbine at 1200 K. Accounting for the variation of specific heats with temperature, determine the minimum mass flow rate of air needed...
