Isi yg di bahas dalam video Laju Reaksi oleh; Pande Ketut Sri Rahayu (32) dari kls F1
*apa sih itu laju reaksi???* Laju reaksi adalah kecepatan proses terjadinya
suatu reaksi, sehingga reaktan habis dan berubah
menjadi produk reaksi.
*Lalu laju reaksi sama aja berbanding dengan apa dong?* sama aja
dengan perbandingan *koefisien reaksi*.
*Ohhh gituuu,,,terus dalam laju reaksi bisa terjadi apa?*
Dalam laju reaksi bisa terjadi Pengurangan konsentrasi zat-zat reaktan
karena berubah menjadi produk per satuan
waktu.
tidak hanya itu bisa juga terjadi penambahan konsentrasi zat-zat produk
karena perubahan reaktan per satuan waktu.
*Kalo gitu gimana dong cara untuk mengamati dengan mudah terjadinya laju reaksi itu? Kasi tau dong:(*
begini cara termudah
dilakukan untuk mengamati laju reaksi.
1) Laju reaksi diamati dari laju pembentukan
gas, dengan mengumpulkannya ke tempat
lain lalu diukur. 2) Laju reaksi diamati dari laju pengendapan
zat, yaitu sampai bagian dasar tabung tidak
terlihat . 3) Laju reaksi diamati sampai pereaksi padat
hilang (reaksi telah selesai).
*Wajib di ingat iyaa...*
laju reaksi pada suatu reaksi yang terjadi melalui
beberapa tahap, tahap yang dijadikan acuan
sebagai laju reaksi adalah tahap yang berjalan
lambat.
*Tidak hanya itu kalian juga wajib mengingat!*
Laju reaksi dicatat per interval waktu tertentu,
misalnya per menit.
*Nilai laju reaksi tersebut nilainya makin lama itu makin kecil* Karena...
1) Jumlah reaktan yang semakin berkurang, dan
pada akhirnya bernilai nol. 2) Jumlah produk yang semakin bertambah dan
pada akhirnya bernilai tetap.
*Beserta 2 contoh bentuk Laju Reaksi*
Contoh yg pertama Korosi atau besi berkarat ( prosesnya lambat ) Contoh yg ke dua Kembang api ( prosesnya cepat )
Hello everyone, let me introduce myself.
Pande Ketut Sri Rahayu, number accent 32.
From class F1.
Okay, here I will show you my chemistry assignment video.
Which is called Fast Reaction.
Okay, let's just watch the video.
Hello, I have a question.
In reaction...
Why is the FB and TikTok like this?
It's not fun.
What is this?
Fast reaction.
What is fast reaction?
What is that?
Why is it called fast reaction?
What is fast reaction?
What do you think it is?
What is it?
Okay, let's just ask Google.
Okay, search for Google.
Oh, I see.
I see.
Fast reaction is...
Hmm, I just found out.
Then, what is fast reaction compared to?
What do you think it is compared to?
Okay, let's just ask Google.
It's fast, practical, and easy to understand.
Okay, let's ask Google.
Oh, I see.
Then, what do you think happens in fast reaction?
Do you know what happens?
Hmm, what do you think happens?
Okay, let's just ask Google.
It's fast, right?
Oh, I see.
Hmm, but...
Then, how to easily observe fast reaction?
Do you know how to easily observe fast reaction?
How do you think it is?
Hmm, okay, let's just ask Google.
Wow, it turns out that it's easy.
The way given by Google.
The real.
Give the easiest.
We ask for the easy, give the easy.
Three more ways.
Hmm, wow.
If so, the faster the reaction, the longer it will definitely get bigger.
Right?
It will definitely get bigger.
Let's check it out.
Why?
How come?
The longer it gets, the smaller it gets.
Why?
How come?
Wait, wait.
I think there's a technical error.
How come?
Oh, I see.
It turns out.
Hmm, yes, yes, yes.
But, in theory, it's pretty good.
But, what about the form of fast reaction?
If we don't know the form, how do we use this theory?
How?
Hmm, just look on TikTok.
Yes, yes, just look on TikTok.
Why can iron rust?
Iron rusts due to the corrosion process that occurs in the metal when exposed to water and oxygen.
Processing.
