In an endothermic reaction energy absorbed during bond breaking is greater than the energy released during bond forming . And energy is absorbed as heat energy so therefore the reaction mixture and the surrounding will become cooler

Great video! I just needed a little more clarification on the profiles. Thanks!

[sheneliperera]

And the temp drops becuz heat energy in the surrounding is absorbed during bond breaking

[adildeen]

Your videos are amazing!! Good job :) !!

Mr Alex I really appreciate your teaching, they've been of help sir. once again thank you very much sir. Please sir I have wace exam and chemistry has been a challenge. Please sir help with solid tutorial on organic chemistry I will appreciate that so much. The exam is just some weeks away.

Mg reacts with 2 mol of HCl, so your reaction equation is unbalanced. But besides that, really helpful. Thanks!

[shaikhsufyan]

No mentioning of activation energy !!!

Thanks bro, but Bob is still against Google+

[tugkeelcompany]

Can you show the pictures of endothermic reaction.

[chabelitanarido]

For a guy, you have lots of colorful pens, which is cool 😂

[shawnrouse]

But why did you choose the Hydrochloric in the 1st place?

[areeqalove]

This is the solution process of exo and Endo pls tell if this is so I can copy in my assignment pls.

[areeqalove]

Y solution process h naw exo or Endo ka m y copy krskti hu ?

[tanisha]

Suppose you have a chemical equation how will you know that it's endothermic or exothermic reaction

[yasinhossainrafi]

Why does the temp drop in endothermic reaction and how?
