Reaction enthalpy

How do you solve the reaction enthalpy of N2(g) + 3F2(g) ---> 2NF3(g)?

One way would be to find the enthalpy of formation for each molecule and subtract the net enthalpy of formation of the products by the net enthalpy of formation of the reactants.

If it didn't give you anything else, you can use the individual formation enthalpy of each molecule (from the back of the book) and use addition and subtraction of the products and reactants to find the net enthalpy.

there are multiple ways to solve this question, it just depends on what information you are given/not given
