National University of Science and Technology NUST is top rated engineering university of Pakistan. NUST was founded in 1991 with an aim of providing quality education. NUST grow up dramatically in a very little time period because of their focus and dedication toward their work. NUST provide vast range of undergraduate and Master’s programs for their students. Due to their high standards and quality of education their fee structure is also high and not everyone is able to afford that. Keeping that in mind they started different scholarship programs for needy students. NUST need based scholarship program welcome every student who doesn’t have enough sources to pay the fee, NUST also provides interest free loans and provides facility of paying fee in installments. But in order to get scholarship in NUST candidates must pass their entry test exam, NUST entry test exam is considered to be the toughest engineering test in Pakistan. Every year thousands of students apply to get admission in NUST through NET. Candidates must prepare themselves fully if they want to secure a seat.
Pakprep.com provides a complete solution for the preparation of any entry test. Pakprep.com is equipped with 15000+ quality MCQ’s which are solved and also with their explanation. We also provide the facility of MOCK test and smart analytics, which help our students to analyze their situation in a better way. We have more than 500 successful students from last year.

Basics of Chemistry
Non-stoichiometric compounds are formed by:
- Only alkali metals
- Only transition elements
- Only noble gases
- None of the above
Only transition elements
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.
Gases, Liquids & Solids
Which of the following properties is anisotropic?
- Melting Point
- Electrical Conductivity
- Geometrical Shape
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.
What is the half-life of a third order reaction if k = 1 and a = 0.2 M?
- 5 s
- 5 s
- 25 s
- 5 s
[t1/2] = 1.5/ka2;
Putting values [t1/2] = 1.5/(0.2)2 = 37.5 s.
