Q1.24
For finding limiting reagent,we first find the number of moles and then divide them by their stoichiometric coefficients.Why?and what is the concept behind that? What we really get after dividing the moles with stoichiometric coefficients?

It's it's very intuitive. It's I think session two or session three or more concept on my playlist.
Hi sir,
Watched the lecture as you said.(Loved it)
But I get a confusion in this step:
After finding the ratio inequality,
I get confused what to do next
Glad it helped!
Thanks sir it helped a lot 🫡🙏

Okay, so here's the thing. Don't treat it like an inequality. Okay, let's be real here. What you should have and what you have. Let's do that. Let's forget the inequality for now. So, you should have 1 is to 3. But now you have 1 is to 2.4. It's just like, you need one slice of, I don't know, like cheese and three slices of bread to make a sandwich. But now instead you have 2.4 slices of bread. So, you can't make the sandwich. So, what is limiting? Limiting is the stuff that's less, right? So, 2.4 is what gets completely used up, whatever that is. So, hydrogen in this case is a limiting reagent. That's it. Khatam. And in what ratio? Well, 2.4 by 3. So, 0.8 of nitrogen gets used up. That's it. So, that ratio gets there. So, if you put it back in that 12. So, 12 hydrogen is the whole thing that gets used up. So, one third of that is the nitrogen that gets used up, which is 4. One more nitrogen is left. Make sense?
