from the following data at 25 degrees celsius...
H2(g) + Cl2(g) → 2HCl(g) (∆H ^0 = -185 kJ)
2H2(g) + O2 → 2H2O(g) (∆H ^0 = -483.7 kJ)
calculate ∆H ^0 at 25 degrees celsius for the reaction below:
4HCl(g) + O2(g) → 2Cl2(g) + 2H2O(g)
a. +299 kJ
b. -114 kJ
c. -299 kJ
d. +114 kJ
e. -86.8 kJ
can someone teach me how to solve this problem? i don't just want the right answer. i really want to learn how to do it. the first correct answer will get a best answer. thank you.
