XV for a given increase in volume (V),the work done can be maximum if P.ext is maximum.For this external pressure should always be less than internal pressure ofgasThese are the conditions of a reversible process. Hence maximum work is doneif carried out under reversible condition.In ...
Similarly, using the appropriate equations for the partial specific internal energy u^i, enthalpy h^i, and entropy s^i, we can show that, for a mixture of ideal gases with constant specific heats, the partial specific properties of gas i in the mixture are the same as the corresponding ...
Explain why the increase in volume for the isothermal expansion of an ideal gas makes a positive contribution to the total entropy change. Entropy Change The entropy is defined as the randomness of the reaction, it is positive if the ...
Now, a final thing to notice is that, positive or negative, the enthalpy of mixing absolute value is always rather small, below 1 kJ/mol. This should agree with practical experience: when you mix water and alcohol together, rarely do you feel them heat up (or cool down). So while thes...
Here, \({{{\mathcal{R}}}\) is the universal gas constant, \({{{\mathcal{T}}}\) is the temperature, α0 is the ratio between the free solvent molar fraction in the solvated and unsolvated states, αi is the ratio between the molar fraction of unbound ions i = +, − ...
The virtually infinite selectivity of metal membranes towards hydrogen is related to the fact that the potential field of the (Pd) metal surface can dissociate only hydrogen among all the other light and heavier gas species. In particular, membranes composed of palladium and its alloys can play ...
