Скачать или смотреть Enthalpy Change, Activation Energy, Catalysts & Temperature // Prelim HSC Chemistry

This video will be the first video for Module 4 as part of the stage 6 Preliminary HSC Chemistry Syllabus. The video will aim to introduce you to the concept of Enthalpy and the two thermochemical natures of reactions.

Timestamp
00:00 Introduction
00:17 Enthalpy
02:03 Energy profiles, activation energy & catalysts
03:07 Temperature Change

Inquiry question: What energy changes occur in chemical reactions?
Conduct practical investigations to measure temperature changes in examples of endothermic and exothermic reactions

What is enthalpy? What are endothermic reactions? What are exothermic reactions? What is activation energy? How do catalysts affect activation energy? Do Endothermic reactions increase or decrease temperature? Do exothermic reactions increase or decrease temperature?
