The question paper for GATE (Graduate Aptitude Test in Engineering) Chemical Engineering Program on which selection in Hindustan Petroleum Corporation Limited is based is as follows:


For a pure liquid, the rate of change of vapour pressure with temperature is 0.1 bar/K in the temperature range of 300 to 350 K. If the boiling point of the liquid at 2 bar is 320 K, the temperature (in K) at which it will boil at 1 bar (up to one decimal place) is ______________


Three identical closed systems of a pure gas are taken from an initial temperature and pressure (T1, P1) to a final state (T2, P2), each by a different path. Which of the following is ALWAYS TRUE for the three systems? (∆ represents the change between the initial and final states; U, S, G, Q and Ware internal energy, entropy, Gibbs free energy, heat added and work done, respectively.)
(A) ∆U, ∆S, Q are same
(B) W, ∆U, ∆G are same
(C) ∆S, W, Q are same
(D) ∆G, ∆U, ∆S are same


For a gas phase cracking reaction A → B + C at 300°C, the Gibbs free energy of the reaction at this temperature is ∆G° = −2750 J/mol. The pressure is 1 bar and the gas phase can be assumed to be ideal. The universal gas constant R = 8.314 J/mol.K. The fractional molar conversion of A at equilibrium is:
(A) 0.44
(B) 0.50
(C) 0.64
(D) 0.80


For a binary mixture of components A and B, NA and NB denote the total molar fluxes of components A and B, respectively. JA and JB are the corresponding molar diffusive fluxes.
Which of the following is true for equimolar counter-diffusion in the binary mixture?
(A) NA + NB = 0 and JA + JB ≠ 0
(B) NA + NB ≠ 0 and JA + JB = 0
(C) NA + NB ≠ 0 and JA + JB ≠ 0
(D) NA + NB = 0 and JA + JB = 0
