How does the enthalpy change for the reverse reaction compare to the enthalpy change of the forward reaction
1. the changes in enthalpy are the same
2. the changes in enthalpy are different in magnitude and sign
3. the changes in enthalpy are the same in magnitude but different in sign.
4. the change in enthalpy of the reverse reaction can not be determined

3. The changes are of equal value, but they have different signs since one way is exothermic and the reverse is endothermic.

q = (mass) (replace in temperature) (certain warmth) exothermic constructive not confident on the specifics of the answer because it is inadequate files. Is the reaction (as written) endo or exo? How will the reaction be utilized interior the Hess' regulation calculation?
