Learn what the activation energy of a chemical reaction is and how it is lowered with the use of catalysts. See some examples of catalysts. Related to this Question Explain how enzymes speed up chemical reactions. What is a factor that could speed up or slow down enzyme speed?
Type of Reaction & Entropy Change: The entropy change during a chemical reaction depends on its nature. For example, the entropy change during a combination reaction is always negative, whereas the entropy change is positive during a decomposition reaction. ...

How does a fuel cell make electricity from hydrogen? What happens in a fuel cell is called an electrochemical reaction. It's a chemical reaction, because it involves two chemicals joining together, but it's an electrical reaction too because electricity is produced as the reaction runs its ...
Explain how a sample of CH_3CH_2CH_2OH could be distinguished from a sample of CH_3COOH by means of a chemical reaction? How to decompose hydrogen peroxide? Explain all the steps. How to prepare 50 % of sulphuric acid from 10 N of sulphuric acid?
Atmospheric methane growth reached an exceptionally high rate of 15.1 ± 0.4 parts per billion per year in 2020 despite a probable decrease in anthropogenic methane emissions during COVID-19 lockdowns1. Here we quantify changes in methane sources and in its atmospheric sink in 2020 compared...
