Hi, in this question we have given the number of moles and the initial volume, the initial pressure.
00:08
Temperature is constant.
00:11
External pressure is also given.
00:13
The final volume is this.
00:15
We need to find out the heat in jule for this reaction.
00:22
From the first law of thermodynamics, we can write change in energy will be equal to heat minus work done.
00:44
As the reaction is proceeding in constant temperature and daily equal to cvm, that is, heat capacity or molar heat capacity at constant volume into dt, as temperature is constant, so dt is 0, that is why daily is also 0.
01:11
From this we can write q will be equal to w.
01:16
Now work done for isothermal process can be written as minus nrt ln v2 by v1...
