mole concept

How do we start solving this? Which equation is to be followed out of the two? The answer is given as 6L

is it something to do with limiting reagent
cuz with 3l of H2 only 1 L of N2 would react for the second reaction
and for first, 3L of N2 will react

TaktOP•6/7/24, 9:47 AM

Will the reaction that takes place depend on the ratios in which we take the reactants?or other conditions?

Keshav•6/7/24, 9:48 AM

yeah it depends on the amount of h2 you take
its in the qs
but there's nothing concrete given
so, I am speculating limiting reagent

iTeachChem•6/7/24, 9:50 AM

i solved a similar q on the doubts with masses

ye aap hi ne poocha tha :) remember

Keshav•6/7/24, 9:51 AM

@iTeachChem why won't the second reaction take place?
It can still react with 1L of N2

Keshav•6/7/24, 9:52 AM

@Takt yeah the first reaction will take place
and form 3L of product
so we are left with 2L of N2
therefore, contraction will be simply
5+3 -2 = 6L

iTeachChem•6/7/24, 10:07 AM

it will :)

iTeachChem•6/7/24, 10:07 AM

na both will take place i feel

iTeachChem•6/7/24, 10:07 AM

the process will be similar to this @Keshav

Keshav•6/7/24, 10:07 AM

but in the solution I checked online they only cared about the first reaction

KKeshav but in the solution I checked online they only cared about the first reaction

iTeachChem•6/7/24, 10:08 AM

interesting

iTeachChem•6/7/24, 10:08 AM

so it is like the Xe and F2 reactions

iTeachChem•6/7/24, 10:08 AM

depending on the ratio of Xe and F2 you get XeF2, XeF4 and XeF6

iTeachChem•6/7/24, 10:08 AM

Noted!

Keshav•6/7/24, 10:09 AM

but its still weird

Keshav•6/7/24, 10:09 AM

They just said, "depending upon the supply of H2'

IiTeachChem ye aap hi ne poocha tha :) remember

TaktOP•6/7/24, 10:14 AM

Yesss, thank you sir
Also
As the products are not gaseous, we can't determine the volume, right? Wouldn't that depend on the density of the liquid formed?

iTeachChem•6/7/24, 10:14 AM

well, volume of gas reduces since gases are being consumed

iTeachChem•6/7/24, 10:14 AM

that is the angle we should be looking at

Keshav•6/7/24, 10:19 AM

By contraction, they mean intial and final volumes of gases we had
in this case, we had 8L of gas intially and after the reaction we were left with 2L of N2
so 8-2L of contraction = 6L
