Hello students in this question we have to find out the total pressure and this total pressure is equal to the sum of the partial pressure of each guess each elements that are present in a reaction.
00:13
Now the given reaction is n2 plus 3h2 it gives 2 nh 3.
00:23
Now in the question it is given that moles of n2 is equal to 1 mole and moles of h2 is equals to 3 mole.
00:37
Now let p0 is equal to the initial total pressure.
00:46
Now, now here we have to find out the partial pressure of each gases.
00:53
Now the partial pressure of n2 is equal to number of moles of n2 upon number of moles of n2 plus number of moles of h2 multiply by the partial pressure.
01:07
So when we find out here we get a value which is 0 .25 p .0.
01:12
Now next we have to calculate the partial pressure of h2.
01:14
It is equals to 3 mole of h2 upon 1 mole of n2 plus 3 mole of h2 multiply by p .0.
01:27
So when we calculate this we get 0 .75 p .0.
01:32
Now next let's draw the ic table for this.
01:35
Now the partial pressure of here comes a partial pressure of n2, partial pressure of h2 and here partial pressure of nh3.
01:43
Now suppose the initial pressure pressure pressure is 0 .25 p .0.
01:48
For this it's to be 0 .75 p .0 and for nh3 it's to be 0.
01:53
Now the change comes to be here change comes to be minus 1.
01:56
Here minus 3x minus 3x because the given is that there are 3 moles of h2.
02:02
To this n h3.
02:06
Next at equilibrium the change comes to be 0 .25 p .0 minus x, 0 .75 p .0 minus 3x and this comes to be same 2x.
02:19
Now now this total pressure is equal to p .0 is equal to p nh3 upon p n2, partial pressure of n2, h2, plus partial pressure of this nh3...
