In the given question, we have to calculate the value of delta gm for two processes.
00:06
So in our first processes, our carbon solid in the form of graphite gets converted into carbon solid.
00:15
So what is happening is the temperature remains constant, but the pressure from one bar has been increased to 325 bar.
00:28
While the temperature in both the case is 298 .15 kelvin and the carbon is in the form of graphite.
00:37
Okay.
00:39
So for this we have to first calculate delta gm.
00:42
So this is our first process.
00:44
So we know that delta gm for these processes is given by our molar volume into our p final minus p initiation.
00:59
Okay.
01:01
So as we know that our molar volume, okay, first we will need to find the molar volume.
01:07
So molar volume will be equals to molecular weight divided by density.
01:13
So molecular weight for carbon is 12.
01:15
Okay.
01:16
It's density is 2 to 5 .0 kilogram per meter cube.
01:21
Okay.
01:22
So we will multiply here by 10 to the power minus 3 to convert this molecular weight into kilogram...
