Transcribed Image Text:Question 7
Use the equations below to find the reaction enthalpy (AH°pn) in kilojoules per mole (kJ/mol) for the following chemical process,
where "X" represents an unknown element:
2X (s) + 3 H2 (g) – X2H6 (g) AH°pn
= ??? kJ/mol
Add the equations below in the correct combination to arrive at the reaction enthalpy in the reaction above.
X2H6 (g) + 3 02 (g) + XOg (s) + 3 H20 (g) AH°- -1941 kJ/mol
2X (s) + 02 (g)
- X203 (s)
AH°- -2668 kJ/mol
(3) 7o + (3) H
+ H20 (g)
AH° - -241.8 kJ/mol
