Hi, here we have to calculate the delta g value for this reaction, that is the change in gives free energy of this reaction.
00:14
Now, it is calculated as delta g is equal to delta h minus t delta s.
00:19
Delta h is the heat of reaction or enthalpy of reaction and delta is s is the change in entropy of reaction.
00:32
Now t here is the temperature, so now t given is 12 .9 degrees celsius, so we need to calculate it in kelvin.
00:39
So it is equal to 12 .9 plus 273 kelvin.
00:44
It is equal to 285 .9 kelvin.
00:50
Now, delta s value is given in joules, so we have to convert it in kilojowl.
00:55
So 77 .87, multiply by 10 -d -to -power minus 3 kilo -joul as 1 jowl is equal to 10 x to power minus 3 kilojoule per kelvin here...
