Calculate the change of enthalpy for the reaction CH4 (g) + NH3 (g) --> HCN (g) +3H2 (g) from the following reactions:
Reaction 1: N2 (g) + 3H2 (g) --> 2NH3 (g) Change in enthalpy: -91.8 kJ/mol
Reaction 2: C (s, graphite) + 2H2 (g) --> CH4 (g) Change in enthalpy: -74.9 kJ/mol
Reaction 3: H2 (g) + 2C (s, graphite) + N2 (g) --> 2HCN (g) Change in enthalpy: +270.3 kJ/mol
Include the following:
1. The numerical answer with correct units.
2. State which reactions, if any, you had to "Flip".
3. State which reactions you had to multiply, if any, to get the correct amount of the compound.
4. Also, include how much you multiplied the reaction by.
