The idea, in English
A catalyst speeds up a chemical reaction without being used up; it is written over the arrow (e.g. MnO2 in making oxygen from H2O2).
Explain in Egyptian Arabic
الـ catalyst بيسرّع الـ chemical reaction من غير ما يتستهلك، وبيتكتب فوق السهم (زي الـ MnO2 في تحضير الـ oxygen من الـ H2O2).
Common misconceptions
- The catalyst is consumed in the reaction.
No. A catalyst changes the rate of the reaction without itself being changed: it is left at the end with the same mass, so it can be used again, e.g. MnO2 in the decomposition of H2O2.
Explain in Egyptian Arabic
لأ، الـ catalyst مش بيتستهلك في الـ reaction: بيرجع في الآخر بنفس الكتلة، وعشان كده ينفع يتستخدم تاني.
