Hello students, let's begin with this question.
00:02
In this question, this reaction is given and on this reaction some questions are given and that questions are based upon the lee -chatelers principle.
00:13
So, according to this principle when a system which is at the equilibrium that is subjected to change certain its parameter like change in the temperature, concentration or pressure or we can say that any external stress is applied then the system will shift in that direction to counteract the change applied.
00:50
So, to counteract the change means that in this case the new equilibrium is established.
00:58
So, in the first part of this question we have to answer that when 0 .2 gram of the sodium dichromate is added to the solution then what would happen to this reaction? so, when this 0 .2 gram of sodium dichromate is added this means that here by adding this the concentration of co4 2 negative ions is increasing as it is forming the nacro4.
01:36
So, this increases so here according to the lee -chatelers principle the equilibrium will shift to counteract this change.
01:45
So, this will shift towards the product side.
01:48
So, the equilibrium this will shift towards the product side.
02:00
Now, in the second part of this question so now here the now the 10 ml 10 .0 ml of 2 molar koh is added now...
