Default Re: GITAM GAT Previous Papers

As per your request I am here giving you previous year paper of GAT exam of Gandhi Institute of Technology And Management (GITAM).

GITAM GAT Exam Paper:

For an irreversible reaction A ----> 2B, the rate is increased by four times when the concentration of A is doubled. The incorrect statement about this reaction is:

1) It is a second order reaction.

2) Half life is independent of initial concentration of A.

3) The unit of the specific rate, k is L mol-1 s-1.

4) Half life is inversely related to the initial concentration of A.

The correct order of ∠FMF bond angles (where M is the central atom) in NSF3, SiF4 and POF3 is:

1) NSF3 > SiF4 > POF3

2) SiF4 > NSF3 > POF3

3) NSF3 > POF3 > SiF4

4) SiF4 > POF3 > NSF3

The outer electronic configuration of metal, M in a diamagnetic complex with the formula, M(NH3)(EtNH2)BrCl is (n-1)d8. It does not give any precipitate with silver nitrate. The correct statement about this complex among the following is:

1) Exhibits optical activity.

2) The metal, M undergoes sp3 hybridization.

3) Can show geometrical isomerism.

4) Its aqueous solution exhibits electrical conductivity.

For the vaporization process of HI, the molar entropy and molar enthalpy are respectively, 89.0 J K-1 mol-1 and 21.16 kJ mol-1. The temperature at which the value of ΔG becomes zero for this process is:

1) 237800 K

2) 273.8 oC

3) 35.2 K

4) -35.2 oC

The incorrect statement regarding the element Ununseptium is:

a) It belongs to group of halogens.

b) It belongs to 7th period of periodic table:

c) It is a radioactive element.

d) It is a strong metal.

(B) Frenkel defect is a dislocation defect
(C) Trapping of an electron in the lattice leads to the formation of F-center
(D) Schottky defects have no effect on the physical properties of solids

Ans. (B, C)

Q. Among the following, the state function(s) is (are)
(A) Internal energy (B) Irreversible expansion work
(C) Reversible expansion work (D) Molar enthalpy

Ans. (A, D)
