ETEA SAMPLE CHEMISTRY QUESTIONS

ETEA stands for Educational Testing and Evaluation Agency, it is an educational entity established in 1998 by KPK government. In order to get admission in the public sector Medical Colleges of KPK, the students have to undergo KPK ETEA entrance test, which is a requirement. Hundreds and thousands of students take this test each year. The test is based on the courses of FSc and A levels including the subjects: Physics, Chemistry, Mathematics and English. ETEA is a highly competitive and challenging test based on the student’s previous knowledge of FSc or A levels.

CHEMISTRY QUESTIONS

TOPIC

Gases, Liquids & Solids

QUESTION

Which of the following properties is anisotropic?

OPTIONS

  • Melting Point
  • Density
  • Electrical Conductivity
  • Geometrical Shape

CORRECT OPTIONS

Electrical Conductivity

EXPLANATION

Physical properties that depend on the direction are called anisotropic properties. The physical properties of crystalline solids like refractive index, coefficient of thermal expansion, electrical and thermal conductivity, and cleavage plane are anisotropic in nature.

Topic

Reaction Kinetics

Question

For homogeneous catalysis reaction between liquids, the catalyst should be of which form?

Options

  • Solid
  • Liquid
  • Gas
  • Can be any of the above

Correct Answer

Liquid

Explanation

In chemistry, homogeneous catalysis is a sequence of reactions that involve a catalyst in the same phase as the reactants. Phase here refers to solid, liquid, vs gas. Most commonly, a homogeneous catalyst is co-dissolved in a solvent with the reactants.

TOPIC

Transition Elements

QUESTION

Transition elements from complexes due which of the following reason?

OPTIONS

  • Para magnetism
  • Vacant d-orbitals
  • Large nuclear charge
  • Small cation size

CORRECT OPTION

Vacant d-orbitals

EXPLANATION

Vacant orbitals of central metal atom or iron are filled by ligands to form metal complexes.

In Chemistry, a coordination complex or metal complex consists of a central atom or ion which is usually metallic and is called the coordination center and a surrounding array of bound molecules or ions that are in turn known as ligands or complexing agents. Many metal containing compounds, especially those of transition metals are coordination complexes.
