A research team led by Professor Hyung-Joon Shin from the Department of Materials Science and Engineering at UNIST has succeeded in elucidating the quantum phenomenon occurring within a triangular ...

The questions in this quiz are suitable for GCSE combined science students studying the effect of concentration and pressure, surface area, temperature, and catalysts on the rate of reaction. If you ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

where two ammonium ions and one bicarbonate ion are formed for each urea molecule that is hydrolysed. In addition, one proton is consumed which raises the pH. When calcium or other divalent cations ...

Theoretical chemists have solved an important mystery about the rates of chemical reactions and the so-called Polanyi rules. The findings reveal why a reaction involving methane does not conform to ...

At the air-water interface, a negatively charged amino acid carries out a nucleophile attack on a gas molecule to convert it into a product. The reaction rate is enhanced due to significant reduction ...

The terms reaction rate, chemical kinetics, and effective collisions are defined. Reaction Rates: The terms reaction rate, chemical kinetics, and effective collisions are defined. Students learn the ...

Baked bread, roasted coffee, and grilled steak owe their enticing smell to a sequence of chemical reactions that was first reported 100 years ago by the French chemist Louis-Camille Maillard. Although ...
