Among the following, the set of parameters that represents path functions, is: i) q + w ii) q iii) w iv) H - T S

Step-by-step solution

State function: It is a property of which value does not depend on the path only depends upon the initial and final point Like: Internal energy U , Gibb's free energy G Path function: Does not depend upon the initial and final point like heat energy q and work done w . A           q + w = Δ U ← definite quantity B           q → Path function C           w → Path function D           &
