Answer 1

Answer #1

4) for calculating enthalpy we should get the desired equation by adding on subtraction the equations from which we have to find enthalpy

So consider al the given enthalpy equations as 1,2,3

equation 1+2

Then reverse equation 3 and then add to equation 1 and 2, we will add the desire equation I.e.

N2H4 + H2 –------ 2NH3

Now

Enthalpy can be calculated as

= (-37)+(-46)+65

=18 kj
