In this question, the motive is to find the flow rates of the component in the exit stream.
00:07
So, let us talk about the reaction and it will be c2h6.
00:12
Now, this is giving us c2h4 and then it will be here plus h2.
00:18
So, firstly, we will talk about the mole balance for hydrogen.
00:23
So, in the mole balance for hydrogen, it can be said that with the help of above reaction, it is clearly seen that 1 mole of ethane will produce 1 mole of hydrogen.
00:38
So here we can write 1 mole of ethane which is c2h6.
00:44
So this is going to produce 1 mole of hydrogen.
00:48
So here we can write 1 mole and then it will be here h2.
00:53
Now we can say that since the exit flow rate of hydrogen is given, so it will be exit flow and then here it is rate.
01:04
Now we can write for hydrogen.
01:07
So this is 40 moles per minute.
01:10
So, if it is 40 moles per minute, then how much of ethane must have reacted? the same amount of ethane must have reacted, right? so here, let us write that ethane and then it will be here reacted.
01:28
So this value will also be equals to 40 moles and then it is per minute.
01:35
Now let us talk about the mole balance for ethane.
01:40
So here we can write that this is the second mole balance and this time we are doing it for ethane that is c2h6.
01:49
So this time the feed rate of ethane is 100 mole per minute.
01:55
So here we can write feed and then it will be here rate and we know the ethane reacted.
02:02
So, we need to find the number of moles of ethane in the exit stream.
02:08
So, the required value for ethane in the exit stream will be, let's write it is exit flow and then it will be here rate and we are talking about ethane...
