Here we are firstly looking at the standard enthalpy change, that is delta h naught is equal to the sum of the moles, delta h formation of the products, subtract the sum, the moles multiplied by the change in entropy of formation of the reactants.
00:21
We can also look at the entropy after looking at the enthalpy.
00:27
So here we have delta s -0, that's equal to the sum, the moles, delta s -f -nought of the products.
00:34
Subtract some of the moles multiplied by delta f's f -0 of the reactants.
00:44
Finally, we have delta g -k -not is equal to delta -h -h -nought minus t -delta -s -0.
00:52
So here we have some equations that we're able to use now.
00:59
And so what we can do is taking a look at our balanced chemical equation, we can calculate the standard enthalpy change using equation 1.
01:11
We're using equation 1.
01:14
We get 0, we get negative 352 .9 kilojoules per mole...
