    Thermodynamic process differ based on the manner in which it is carried out. a) Distinguish between reversible and irreversible processes. b) Calculate the amount of work done when 2 moles of a gas expands from a volume of 2 L to 6 L isothermally and irreversibly against a constant external pressure of 1 atm.

    The change in internal energy (U) can be brought about in two ways: (i) Either by allowing the heat of flow into the system or out of the system (ii) By doing work on the system or the work done by the system Using the symbol q to represent heat transferred to system and using work done by the system - w, we can represent the internal energy change of a system Delta U, as : q = Delta U + (-w) (First law of thermodynamics) If the reaction is caried out in a closed container with constant volume so that Delta V = 0 Hence, q _(1) = Delta U On the other hand, if a reaction carried out in open vessel that keeps the pressure contans and allows the volume of the system to change freely. In such case, Delta V ne 0 and - w = P. Delta V. Hence, q _(B) = Delta U + p Delta V Also q _(P) = q _(v) + Delta_(g) RT As reactions carried out at constant pressure are so common, the heat change for such preocess is given a special symbol Delta H, called the enhalpy change of the reaction .
