0:41 exothermic and endothermic reactions

2:03 enthalpy change, ∆H (extended)
2:33 activation energy (extended)
3:10 reaction pathway diagrams (extended)
3:54 bond breaking and bond making (extended)
4:47 calculate enthalpy change using bond energies (extended)
Core content:
1) State that an exothermic reaction transfers thermal energy to the surroundings leading to an increase in the temperature of the surroundings
2) State that an endothermic reaction takes in thermal energy from the surroundings leading to a decrease in the temperature of the surroundings
3) Interpret reaction pathway diagrams showing exothermic and endothermic reactions
Extended content:
4) State that the transfer of thermal energy during a reaction is called the enthalpy change, ∆H, of the reaction. ∆H is negative for exothermic reactions and positive for endothermic reactions
5) Define activation energy, Ea, as the minimum energy that colliding particles must have to react
6) Draw and label reaction pathway diagrams for exothermic and endothermic reactions using information provided, to include:
(a) reactants
(b) products
(c) enthalpy change of the reaction, ∆H
(d) activation energy, Ea
7) State that bond breaking is an endothermic process and bond making is an exothermic process and explain the enthalpy change of a reaction in terms of bond breaking and bond making
8) Calculate the enthalpy change of a reaction using bond energies

for this specific topic theres a lot of different categories of stuff to take in. Does anyone know some acronyms or just a way to help me remember everything more efficiently
I recommend practicing lots of past questions on the topic.
@@igbiocomplete alright thanks

G.O.A.T teacher
✌🏻
Please make a video on paper 4 extended theory !! Thanks for creating this amazing content here on your channel!
Plz, could you solved past paper 6 chemistry for October November if possible ❤ I watch your biology past papers they are easy to understand and appropriate answers
Amaaazing keep going
Thank you, I will!
Sir thank you very much Iris reflex was very confusing for me
You're welcome :)
Hello Sir. What are your predicted questions for O-Level Biology paper 2, variant 2 for Oct/Nov 2024 exams.
sir thank you very much for your explaination, my class is just so noisy its hard to focus so i tend to watch videos like yours for my help
Welcome 👍🏻
I have my forecast 1 tomrw speedrunning these (ur W)
will u do for AS Level chem?
Unlikely!
Your videos are great. Please upload rest of the IGCSE Chemistry syllabus as early as possible. If possible also cover IGCSE Physics and Environmental Management syllabus.
Thank you. Physics is possible.
@@igbiocomplete thanks
one of the best tutors out there!!
Sir Please make more vids about chem , the previous bio vids are the only thing which helps me to score A*
Emard Via
I bought complete course best notes thank you so much for your hard work
Much appreciated 👍🏻
