Which of the following are not path functions? I. H-T S II. W II. q IV. q+W

Options

  1. AI and III
  2. BI, II, IV
  3. CII, III and IV
  4. DI and IV

Correct answer

D. I and IV

Step-by-step solution

Thermodynamic parameters which depend only on the initial and final states of system are called state functions, such as enthalpy (I I=q+W) , Cibb's free energy (C=H-T S) . Whereas, thermodynamic parameters which depend on the path by which the process is performed and not on initial and final states, are called path functions, such as work done (W) , heat (q) etc.
