GIKI SAMPLE CHEMISTRY QUESTIONS FROM PAKPREP.COM

Ghulam Ishaq Khan Institute of Information Technology (GIKI) is ranked among top engineering universities of Pakistan and also known as worldwide due to their quality of education. GIKI was established in 1988 by former President of Pakistan Ghulam Ishaq Khan. Their main motive is to provide quality education and lift youth of Pakistan by providing them carrier opportunities. Currently GIKI has six different departments focusing on science and engineering. Same like other universities their eligibility criteria is not very high and you only need 60% marks in FSc to be eligible for any program in GIKI. Due to their high standards their fee structure is also very high and not every candidate can afford it, so keeping that in mind they also provide scholarships to needy students.

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.

Solutions

Question:

If we have 450g of a NaCL solution that is 35 NaCL w/w %. What is the mass of NaCL?

Options:

  • 128.5 g
  • 129.5 g
  • 157.5 g
  • 131.5 g

Correct Answer:

157.5 g

Explanation:

% by weight = (Mass of solute/Mass of solution) * 100

35 = (X/450) *100

X = 35 * 450/100 = 157.5 g

Basics of Chemistry

Question:

Non-stoichiometric compounds are formed by:

Options:

  • Only alkali metals
  • Only transition elements
  • Only noble gases
  • None of the above

Correct Option:

Only transition elements

Explanation:

Binary transition metal compounds, such as the oxides and sulfides, are usually written with idealized stoichiometry’s, such as FeO or FeS but these compounds are usually cation deficient and mostly never contain a 1:1 cation:anion ratio. Thus a substance such as ferrous oxide is actually a nonstoichiometric compound with a range of compositions.
